Shane - point taken. In an attempt to get this resolved, here is
proposed wording to the RDFa Syntax Document:


===== Section Processing non-prefixed CURIEs in @rel/@rev

A CURIE is considered a 'non-prefixed CURIE' if there is no namespace
defined and no preceding colon. An example of a 'non-prefixed CURIE' is
rel="next" or rev="glossary". To provide compatibility with current
semantics expressed in XHTML documents, certain non-prefixed CURIEs MUST
set the predicate for generated triples when used in @rel and @rev.

These non-prefixed CURIEs are:

alternate, appendix, bookmark, chapter, contents, copyright, glossary,
help, icon, index, meta, next, p3pv1, prev, role, section, subsection,
start, and up.

When processing these CURIEs, the parser must prepend the
http://www.w3.org/1999/xhtml/vocab# namespace to the beginning of the
'non-prefixed CURIE' in the generated triple. For example, rel="next"
becomes http://www.w3.org/1999/xhtml/vocab#next. To illustrate,

<a rel="next" href="http://example.org/page2.html">

should generate the following triple:

      <http://example.org/page2.html> .

===== Section 5.3, Step #4 (addition):

'Non-prefixed CURIE's are processed by prepending the
http://www.w3.org/1999/xhtml/vocab# namespace to each predicate that is
a recognized 'non-prefixed CURIE'. A list of all valid non-prefixed
CURIEs is available in Section


Mark, what are the issues that you can see with the text above?
