This presupposes the necessity of reflecting the message's namespaces
in the content-type; why is this necessary? Defining a content-type
always involves a tradeoff in the granularity of information
available. IIRC, the discussion you reference was in the context of
replacing SOAPAction with something in the content-type, which is not
the intent here (based upon our resolution of issue 95).

application/soap+xml says, roughly; 

  This is a format that isn't really interesting for humans to read,
  as it's intended for machines.  It follows the 'SOAP' format, which
  happens to be based upon xml.

IMHO this is about the amount of information that's appropriate. I'd
also be happy with application/soap. 

Cheers,
