Re: GRDDL RDFa transformation tests results

Hello Fabien.  I was working on a general purpose RDFa -> RDF/XML
modality for an Atom feed over the weekend and used this transformation
stylesheet (or the one in the GRDDL WG repository:
grddl-wg/td/RDFa2RDFXML_v_0_7.xsl). I had to make some changes to get it
to work and thought you might be interested.  I didn't commit the
changes, below is a diff:

In particular: 1) The default value for the $url is an empty string.
The way it was before, it was not a valid XPath expression and 2)
<xsl:value-of/> cannot be used within <xsl:text>
(http://www.w3.org/TR/xslt#section-Creating-Text)

I also wondered if the lack of support for blank node CURIES (i.e.,
[_:a]) was because this is an 'unstable' feature in RDFa?

Otherwise, the transform worked wonderfully!

Yes, I was going to ask about this as well, but I notice there is an
ongoing discussion about it in public-rdf-in-xhtml-tf@w3.org :)
