Yet another implementation

When I started at Mark Logic, my getting-to-know-XQuery project was writing
an RDFa parser. This weekend I cleaned it up enough to talk about it.

It¹s implemented in 100% XQuery 1.0 and follows the Functional RDFa pattern
<http://rdfa.info/wiki/Functional_RDFa>
(which I now need to update)

Be gentle on the server. It¹s up at
<http://rdfa.marklogic.com:82/rdfa_extract.xqy?url=>

Right now it¹s green across the Crazy Ivan board, except for some XML
Literal tests. At least several of these seem OK to my eyeballs, but I
welcome any details.

I anticipate making the source available under an open source license in the
near future.

Thanks! -m

P.S. The test suite is a great piece of work. Congrats to all.
