1.3. Differences from v2 to v3 1.3. Differences from RFC 7991 in This Document
This is a (hopefully) complete list of all the technical changes
between [RFC7991] and this document.
o Changed the text about what this draft obsoletes and updates.
o Allow <blockquote> as a child of <aside> and <li>.
o Removed "It is an error to have both a "src" attribute and content
in the <artwork> element." from Section 2.6.6.
o Added <toc>, and <u> elements.
o Changed the "hanging" attribute of <dl> to "newline".
o Added the "indent" attribute to <dl>.
o Added the "align" attribute to <table>. Made the table title
centered under the table.
o The <name> element now allows many more elements inside of it.
o Redefined <references> to allow <references> within it. In the
typical case, an outer <references> will be used to hold an inner
<references> for normative references and an inner <references> to
hold informative references.
o Un-deprecated metadata attributes on the <rfc> element (with the
intent to restore v2 semantics of <seriesInfo> as well).
o Added <contact> element.

2.44. <relref>
Represents a link to a specific part of a document that appears in a
<reference> element. Formatters that have links (such as HTML and
PDF) render <relref> elements as external hyperlinks to the specified
part of the reference, creating the link target by combining the base
URI from the <reference> element with the "relative" attribute from
this element. The "target" attribute is required, and it must be the
anchor of a <reference> element.
The "section" attribute is required, and the "relative" attribute is
optional. If the reference is not an RFC or Internet-Draft that is
in the v3 format, the element needs to have a "relative" attribute;
in this case, the value of the "section" attribute is ignored.
An example of the <relref> element with text content might be:
See
<relref section="2.3" target="RFC9999" displayFormat="bare">
the protocol overview</relref>
for more information.
An HTML formatter might generate:
See
<a href="http://www.rfc-editor.org/rfc/rfc9999.html#s-2.3">

for more information.
Note that the URL in the above example might be different when the
RFC Editor deploys the v3 format.

Content model: only text content.
2.44.1. "displayFormat" Attribute
This attribute is used to signal formatters what the desired format
of the relative reference should be. Formatters for document types
that have linking capability should wrap each part of the displayed
text in hyperlinks. If there is content in the <relref> element,
formatters will ignore the value of this attribute.
"of"
A formatter should display the relative reference as the word
"Section" followed by a space, the contents of the "section"
attribute followed by a space, the word "of", another space, and
the value from the "target" attribute enclosed in square brackets.
For example, with an input of:
See
<relref section="2.3" target="RFC9999" displayFormat="of"/>
for an overview.
An HTML formatter might generate:

Note that "displayFormat='of'" is the default for <relref>, so it
does not need to be given in a <relref> element if that format is
desired.
"comma"
A formatter should display the relative reference as the value
from the "target" attribute enclosed in square brackets, a comma,
a space, the word "Section" followed by a space, and the "section"
attribute.
For example, with an input of:
See
<relref section="2.3" target="RFC9999" displayFormat="comma"/>,

A formatter should display the relative reference as the value
from the "target" attribute enclosed in square brackets, a space,
a left parenthesis, the word "Section" followed by a space, the
"section" attribute, and a right parenthesis.
For example, with an input of: This is the root element of the xml2rfc vocabulary.
See Processors distinguish between RFC mode ("number" attribute being
<relref section="2.3" target="RFC9999" displayFormat="parens"/> present) and Internet-Draft mode ("docName" present and "number"

neither "number" nor "docName" can be useful for producing other
types of documents but is out of scope for this specification.

2.62. <u>
In order to insert Unicode characters in contexts that don't
explicitly allow Unicide, the Unicode string is enclosed within an
<u> element. The element will be expanded inline based on the value
of a "format" attribute. This provides a generalised means of
generating the 6 methods of Unicode renderings listed in [RFC7997],
Section 3.4, and also several others found in for instance the RFC
Format Tools example rendering of RFC 7700.

Content model: only text content.
2.62.1. "anchor" Attribute
Document-wide unique identifier for this <u> element.
2.62.2. "ascii" Attribute
The ASCII equivalent of the content, to be used if the "ascii"
keyword is used in the "format" specification.
2.62.3. "format" Attribute
Default value: "lit-name-num"
The "format" attribute accepts either a simplified format
specification, or a full format string with placeholders for the
various possible Unicode expansions.
The simplified format consists of dash-separated keywords, where each
keyword represents a possible expansion of the Unicode character or
string; use for example "<u "lit-num-name">foo</u>" to expand the
text to its literal value, code point values, and code point names.
A combination of up to 3 of the following keywords may be used,
separated by dashes: "num", "lit", "name", "ascii", "char". The
keywords are expanded as follows and combined, with the second and
third enclosed in parentheses if present:
ascii
The value of the 'ascii' attribute on the <u> element
char
The literal element text, without quotes
lit
The literal element text, enclosed in quotes
name
The Unicode name(s) of the element text
num
The numeric value(s) of the element text, in U+1234 notation
In order to ensure that no specification mistakes can result for
rendering methods that cannot render all Unicode code points, "num"
MUST always be part of the specified format.
In order to provide for cases where the simplified format above is
insufficient, without relinquishing the requirement that the number
of a code point always must be rendered, the "format" attribute can
also accept a full format string. This format uses placeholders
which consist of any of the key words above enclosed in curly braces;
outside of this, any ascii text is permissible. For example,
will be rendered as
As for the simplified format, "num" MUST always be part of the
specified format in order to ensure that no specification mistakes

Represents a link to a specific part of a document that appears in a
<reference> element. Formatters that have links (such as HTML and
PDF) render <relref> elements as external hyperlinks to the specified
part of the reference, creating the link target by combining the base
URI from the <reference> element with the "relative" attribute from
this element. The "target" attribute is required, and it must be the
anchor of a <reference> element.
The "section" attribute is required, and the "relative" attribute is
optional. If the reference is not an RFC or Internet-Draft that is
in the v3 format, the element needs to have a "relative" attribute;
in this case, the value of the "section" attribute is ignored.
An example of the <relref> element with text content might be:
See
<relref section="2.3" target="RFC9999" displayFormat="bare">

for more information.
An HTML formatter might generate:

Content model: only text content.
3.13.1. "displayFormat" Attribute
This attribute is used to signal formatters what the desired format
of the relative reference should be. Formatters for document types
that have linking capability should wrap each part of the displayed
text in hyperlinks. If there is content in the <relref> element,
formatters will ignore the value of this attribute.
"of"
A formatter should display the relative reference as the word
"Section" followed by a space, the contents of the "section"
attribute followed by a space, the word "of", another space, and
the value from the "target" attribute enclosed in square brackets.
For example, with an input of:
See
<relref section="2.3" target="RFC9999" displayFormat="of"/>
for an overview.
An HTML formatter might generate:
See
<a href="http://www.rfc-editor.org/info/rfc9999#s-2.3">
Section 2.3</a> of
[<a href="#RFC9999">RFC9999</a>]
for an overview.
Note that "displayFormat='of'" is the default for <relref>, so it
does not need to be given in a <relref> element if that format is
desired.
"comma"
A formatter should display the relative reference as the value
from the "target" attribute enclosed in square brackets, a comma,
a space, the word "Section" followed by a space, and the "section"
attribute.
For example, with an input of:
See
<relref section="2.3" target="RFC9999" displayFormat="comma"/>,
for an overview.
An HTML formatter might generate:
See
[<a href="#RFC9999">RFC9999</a>],
<a href="http://www.rfc-editor.org/info/rfc9999#s-2.3">
Section 2.3</a>, for an overview.
"parens"
A formatter should display the relative reference as the value
from the "target" attribute enclosed in square brackets, a space,
a left parenthesis, the word "Section" followed by a space, the
"section" attribute, and a right parenthesis.
For example, with an input of:
See
<relref section="2.3" target="RFC9999" displayFormat="parens"/>
for an overview.
An HTML formatter might generate:
See
[<a href="#RFC9999">RFC9999</a>]
(<a href="http://www.rfc-editor.org/info/rfc9999#s-2.3">
Section 2.3</a>)
for an overview.
"bare"
A formatter should display the relative reference as the contents
of the "section" attribute and nothing else. This is useful when
there are multiple relative references to a single base reference.
For example:
See Sections
<relref section="2.3" target="RFC9999" displayFormat="bare"/>
and
<relref section="2.4" target="RFC9999" displayFormat="of"/>
for an overview.
An HTML formatter might generate:
See Sections
<a href="http://www.rfc-editor.org/info/rfc9999#s-2.3">
2.3</a>
and
<a href="http://www.rfc-editor.org/info/rfc9999#s-2.4">
Section 2.4</a> of

3.13.2. "relative" Attribute
Specifies a relative reference from the URI in the target reference.
This value must include whatever leading character is needed to
create the relative reference; typically, this is "#" for HTML
documents.
3.13.3. "section" Attribute (Mandatory)
Specifies a section of the target reference. If the reference is not
an RFC or Internet-Draft in the v3 format, it is an error.
3.13.4. "target" Attribute (Mandatory)
The anchor of the reference for this element. If this value is not
an anchor to a <reference> or <referencegroup> element, it is an
error. If the reference at the target has no URI, it is an error.

The following rules prevent this overlap: The following rules prevent this overlap:
o "pn" for regular sections always has the format "s-nnn", where o "pn" for regular sections always has the format "s-nnn", where
"nnn" is the section number, or the appendix identifier (which "nnn" is the section number, or the appendix identifier (which
starts with a letter). For example, this would be "s-2.1.3" for starts with a letter). For example, this would be "s-2.1.3" for
Section 2.1.3 and "s-a" for Appendix A. For the <abstract> Section 2.1.3 and "s-a" for Appendix A. For the <abstract>
element, it is always "s-abstract". For the <note> element, it is element, it is always "s-abstract". For the <note> element, it is
always "s-note-nnn", where "nnn" is a sequential value. For always "s-note-nnn", where "nnn" is a sequential value. For
sections in the <boilerplate> element, it is always sections in the <boilerplate> element, it is always "s-
"s-boilerplate-nnn", where "nnn" is a sequential value. boilerplate-nnn", where "nnn" is a sequential value.
o "pn" for <references> elements has the format "s-nnn". It is o "pn" for <references> elements has the format "s-nnn". It is
important to note that "nnn" is a number, not letters, even though important to note that "nnn" is a number, not letters, even though
the <references> appear in the back. It is the number that is one the <references> appear in the back. It is the number that is one
higher than the highest top-level section number in <middle>. If higher than the highest top-level section number in <middle>. If
there are two or more <references>, "nnn" will include a dot as if there are two or more <references>, "nnn" will include a dot as if

"ttt" is the slugified item (plus a hyphen and the slugified "ttt" is the slugified item (plus a hyphen and the slugified
subitem if there is a subitem), and "nnn" is the instance of that subitem if there is a subitem), and "nnn" is the instance of that
item/subitem pair. For example, this would be "i-foo-1" for item/subitem pair. For example, this would be "i-foo-1" for
"<iref item='foo'>" and "i-foo-bar-1" for "<iref item='foo' "<iref item='foo'>" and "i-foo-bar-1" for "<iref item='foo'
subitem='bar'>". subitem='bar'>".
o "pn" for <table> elements always has the format "t-nnn", where o "pn" for <table> elements always has the format "t-nnn", where
"nnn" is the table number. For example, this would be "t-5" for "nnn" is the table number. For example, this would be "t-5" for
Table 5. Table 5.
o "pn" for all elements not listed above always has the format o "pn" for all elements not listed above always has the format "p-
"p-nnn-mmm", where "nnn" is the section number and "mmm" is the nnn-mmm", where "nnn" is the section number and "mmm" is the
relative position in the section. For example, this would be relative position in the section. For example, this would be
"p-2.1.3-7" for the seventh part number in Section 2.1.3. "p-2.1.3-7" for the seventh part number in Section 2.1.3.
o "slugifiedName" always has the format "n-ttt", where "ttt" is the o "slugifiedName" always has the format "n-ttt", where "ttt" is the
text of the name after slugification. For example, this would be text of the name after slugification. For example, this would be
"n-protocol-overview" for the name "Protocol Overview". The "n-protocol-overview" for the name "Protocol Overview". The
