I think [1] this is a valuable contribution. However, I'm having
difficulties the design decision 5.2 understanding:

'No new attributes added to XHTML+RDFa 1.0. To markup graphs a new attribute
is required, but this document does not define what that attribute is
called. Instead the producer and consumer of an XHTML document must come to
a private agreement as to which attribute is used. Markup language
specifications that decide to adopt the techniques described in this
document may define such an attribute for usage in that particular

You rightly conclude that we very likely need a new attribute but then state
that 'this document does not define what that attribute is called'. Hm. I
think this is too much relying on a convergent market. I can't see how this
should scale.

Howsoever, I've updated [2] to keep track of this proposal. Let's see how it

Keep up the good work!
