The Basic Profile Working Group in Web Services Interoperability
Organization (WS-I)  is looking at the MIME bindings from WSDL 1.1.
There is a proposal within the WG to get rid of mime:mimeXml as it is
thought to be potentially confusing, would simplify things and is
syntactic sugar for -
<mime:content type="text/xml" ... />
This email is to solicit input from implementers, as to, whether there
are any implementations that implement mime:mimeXml and/or find it
Thanks and regards.
