This is only semi-related to this question, but profile parameters are  
unreliable. OMA did something similar with a Mobile Profile of XHTML (an  
almost pure subset of XHTML), using the XHTML content type. As a  
consequence we tested parameters and found them somewhat unreliable. I  
don't remember the details but clients didn't always lop the parameters  
off, servers didn't always serve them.

I guess this just goes to show that if a feature is unused long enough  
interoperability suffers (that it is unused may also indicate that this  
wasn't such a good idea but that is another debate).
