Well, by the time the method has been invoked by the JAXRS runtime the
providers have already been checked, and the job of MultipartProvider is to
give users access to individual parts and let them parse XML bits if such
exist, deal with binary parts whichever way they prefer.

This is what happening when parameters represent individual parts.
But as I said, enhancing MultipartProvider a bit would make sense.

If you have say a single XML part only or any fixed number of XMl parts
followed by a variable number of
some other parts, then you can do :
unpack(@Multipart("root", text/xml) MixedString str, List<Attachment> atts)
{
}
in the list the 1st entry will represent the already read MixedString, and
others will point to some binary ones
