It _is_ for private use, as currently defined.

No comment on that.  But I meant cleaner from HTML's point of view --
separate attributes for separate things, where data-* is for
site-specific stuff that author has made up and the well-known RDFA has
its own.  That makes it easier for authors to see what's what, easier
for RDFA consumers to see what they have to parse, and easier for
teachers to teach the purpose of each attribute -- especially if they
wish to teach private attributes without mentioning RDFA, or _vice
versa_.

(And it avoids the risk of the Retired Divorced Female's Association[*1]
minting a data-* attribute which clashes.)

Why do you think it's preferably to commingle these things?

If the consensus is to support RDFA , then why do you believe the
working group would be against providing syntax for it?

(Of course if the consensus isn't to support RDFA then your suggested
change to expand the scope of data-* to support it will be unnecessary.
Having consenus for the semantics of RDFA but not for providing syntax,
any syntax, seems peculiar.)
