Yes it is, but it's now pretty widely understood that HTML (with or 
without embedded scripts or objects) can be dangerous on the client.

I don't think there's the same understanding of vulnerabilities on the 
server side: if you POST and HTML document to a server you wouldn't 
normally expect it to attempt to retrieve images or execute embedded 
scripts or objects. OTOH, with an XML POST to a validating XML 
processor, retrieval of referenced external enities is precisely what's 
going to happen in many cases.
