ACTION-71: 3.2.3 for non-embedded content

Here's what we have for 2.4.5. Note that the text we reached consensus on
used "documents". As we agreed subsequently to use "non-embedded content"
rather than documents, I have made the substitution. A minor bit of
additional editing was required but I think the original meaning is
preserved.

<2.4.5 guidance for non-embedded content>

This applies to non-embedded content directly as written, and as described
in INTENT from Understanding WCAG 2.0 (above) replacing "web pages" with
"non-embedded content" and replacing "set of web pages" with "set of
non-embedded content". A set of non-embedded content is a group of
non-embedded content that is 1) published together, and 2) labeled as a set
within at least one member of the set. Republishing previously published
non-embedded content as a collection does not constitute a set of
non-embedded content.

</2.4.5 guidance for non-embedded content>

Adapting this for 3.2.3 .....

<proposal for 3.2.3 guidance>

This applies to non-embedded content directly as written, and as described
in INTENT from Understanding WCAG 2.0 (above) replacing "multiple Web pages
within a set of Web pages" with "multiple members of a set of non-embedded
content". A set of non-embedded content is a group of non-embedded content
that is 1) published together, and 2) labeled as a set within at least one
member of the set. Republishing previously published non-embedded content
as a collection does not constitute a set of non-embedded content.

</proposal for 3.2.3 guidance>

The WCAG 2.0 intent also needs some editing. I'm working on that as part of
ACTION-70.

Any comments on this proposal before I put it on a survey?
