> I don't understand the change in XHTMLMP case. Why downgrade application/xml, but not application/xhtml+xml?

Two motivations:

1) The heart of this issue is making sure application/xml is downgraded below text/html. How text/html and application/xhtml+xml are arranged is, relatively, inconsequential. I did not want to change any more than was necessary to resolve the fundamental issue of this ticket.

2) (This is *much* more nit picking and *much* less important.) 'application/xhtml+xml;profile='http://www.wapforum.org/xhtml' is not equivalent to 'application/xhtml'. It implies the server should only serve application/xhtml+xml if it can do so with that specific WAP profile. Technically, by the HTTP spec, the XHTMLMP accept header prioritizes a generic 'application/xhtml' below 'application/xml' because it falls under the expansion of */*. In practice, servers often ignore the profile parameter.

> I suggest leaving XHTMLMP unchanged, for people who care about it (if any) to consider consequences of changing the Accept string.

I don't know who or what uses the XHTMLMP case, and I don't have a problem leaving it alone, but I do believe it is a win to get HTML > XML in any case. Let me know if you need me to resubmit sans the XHTMLMP change for this to continue making progress.
