That's not why I'd snub it. I'd snub becuase you're using XML to 
tunnel yet another RDF syntax through element content, instead of 
levaraging XML to create yet another RDF syntax. That strikes me as 
pointless - as I have to write a tokenizer just for the element 
content, I'd rather not have to fire up an XML parser just for the 
sake of getting at it. The XML is redundant.

Not handy. RDF was a usecase for namespaces.

Agreed. And Qnames in element content have  higher cost (imo).

One of them isn't neccessary.
