Looking at https://www.html5rocks.com/en/tutorials/track/basics/
it seems JSON can be used, no idea if content type is different or not 
for that.

Mixing XML and HTML is not a good idea. Would it not be easier to have 
the server send out proper XML instead of hTML? Valid XML is also valid 
HTML (the reverse is not always true).
And if XML and HTML is giving you issues then use JSON instead.
I did not see JSON mentioned in the W3C spec though.

If a XML document is being served with unclosed tags then it's not valid 
XML, so it's no wonder if that then causes issues.
