François-Paul Servant has a patch that makes Tabulator's RDF parser work in IE 6 
and 7. It is concerned just with the parser, not with all of Tabulator, but it's 
a nice step towards making Tabulator and its support libraries more compatible 
with other browsers.

I'm not the author of this patch, I just want to bring it to the Tabulator 
developers' attention.
