I think that is in terms of writing XML matching the RDF/XML Node/Arc
striping; mixed content really grates badly with that.

That's for some embedding thing.

What?  I've just noticed rdf:ID inside the XHTML bit.  That's not
going to be noticed by an RDF parser.  It only deals with
<rdf:RDF> <rdf:RDF/> blocks.  

We haven't spent a lot of time considering mixing these things like
this.  Sounds more like a web architecture issue.  For the TAG.  Ha ha.

That particular form of words is something I commented on in the WG
myself.  There is no rdf-wrapper element, that is just an example of
how to compare XML literals using XML canonicalization.  If you could
write a comment on this to the www-rdf-comments list, the editors
should respond.

Great.
