why not new attributes? (RDFa model and xml:id)

[Bruce D'Arcus <bruce.darcus@OpenDocument.us>]

Hi All,

I think we made good progress today on agreeing on a number of points, 
and narrowing down where we disagree on to effectively a single point 
(great!).

A suggestion on that follows ...

If you copy-and-paste to another document, you lose the semantics (and 
might end up with id clashes if not careful). Those ids are meaningless 
without the additional RDF/XML metadata in the package.

In the RDFa approach, you use the same number of attributes, but the 
semantics are right there.

I'd like to return to a question we really didn't have time for:

Why from an implementation standpoint might it be a problem to add new 
metadata attributes?

Suggestion, then (and Patrick just said something similar; just 
suggesting to put it on a dedicated wiki page):

If people still want to persist with the xml:id-only approach (which I 
do not support), I'd suggest they document it with use case examples on 
a new page on the wiki.

We can reserve the existing page for the hybrid approach, and then 
compare them.
