Hi Karen, My guess is that the plugins support Microdata and RDFa while the hosted pyRDFa only supports RDFa. The code example in your other email has attributes "itemscope" and "itemtype"; these are Microdata attributes. RDFa defines "typeof" and uses "rel", "rev" and other attributes to encode RDF in HTML. RDFa parsers treat stylesheet links in a special way as you have seen, just like they may include the page title as dc:title. (This is from the top of my head, everything can be found in the RDFa Primer [1] and Core specification [2].)
