Hi Rick,

I think adding parts of RDFa into your XML without turning the whole XML 
into some kind of XHTML document will not help much.

If you want to use RDFa and make your data part of the Semantic Web, why 
don't you add more RDFa to your current HTML pages? I see that they do not 
contain all of the data in your XML file, but still there is some valuable 
information in the tables that is still without semantic markup.

In case that the HTML and XML are generated from the same databases (and 
this seems to be the case), you could also make the information that is 
currently only available in the XML version available in the HTML version. 
If you want to hide the details from the reader, but make it available to 
the machines, then you  can use 'hidden' RDFa.

Just some ideas.
