Once again...that is assuming that it is possible to serialise the
same graph in two different ways.

I feel the same way, though...I'm no longer sure what you are arguing.

I said in response to Johannes that we needed to be clearer about our
XML literal support, but the problem with that is that it requires the
processor to do quite a bit of work.

I thought that you and Ben were saying that this is unnecessary, and
that all an RDFa parser had to do was to store the mark-up unchanged.

So since then, I thought we have been discussing whether that is a
correct interpretation of XML literals in the RDF Concepts document.

However, in your other email you said:

> - an informative note may have to be added to the syntax text warning
> implementers that they have to add the necessary namespaces

But that is hardly a side issue...it's the very thing we're
discussing--that is canonicalisation.

So if you are now saying that in order to support rdf:XMLLiterals, we
need to point out that the RDF graph produced by an RDFa parser would
have XML literals in, which *by definition* are in Exclusive
Canonicalised Form, then I can live with that.

I'm increasingly convinced that we should stay away from XML literals,
but if the group is happy with this answer, then let's go with it. My
point is simply that if we are going to 'do' XML literals, they need
to be done properly.
