I have no problem with that, but I'm not the one you have to convince.  :)

It might be useful to put that in the wiki.  But note that it would 
likely be less useful to support generic XML if there's no clear way 
that it should be supported (how it's presented, specific APIs, etc.). 
SVG and MathML are both well-known solution sets.  We'd need to have a 
default behavior for "unknown content".
