Did you try any of the other curl commands I provided?

I continue to get the same results when I test... which is to 
say, success or failure is determined by the first listed MIME 
type, with no impact from quality ratings, nor from the fact 
that application/xhtml+xml appears in every request and *is* 
supported.

The tools you've tested succeeded ... but that tells us nothing 
of whether the server is behaving properly, nor whether it will
deliver success to any other tools.
