My last email explained why this is factually wrong. Did you miss it?

RDFa did not add anything more to sniff in HTML: you're assuming that
(@profile, @rel) is all you need to determine @rel, and I'm pretty sure
that's incorrect.

Take GRDDL, which is a REC, and which can be implemented as an HTML4
@profile. (And which was led by Dan Connolly, whom I trust to know what
@profile means.) To make sense of @rel in GRDDL, you're instructed to
look at <link rel="transformation" href="specificTransformation.xsl">,
which itself tells you *how* to interpret @rel.

What is the difference between this level of indirection and that of RDFa's?
