Here it is.  I will also post my summary of the discussion at the xml-dev 
mailing list very soon.

(3) A new parameter "externalid" for text/xml and application/xml

This parameter specifies the externalID from the DOCTYPE of the XML
document (if the DOCTYPE is present).  Examples would be:

Content-type: text/xml;
   externalid="http://www.foo.com/whizzy.dtd";
or
Content-type: application/xml; charset="utf-16be";
   externalid="-//IETF//DTD vCard v3.0//EN"

Note: None of the above proposals handle non-monolithic XML documents very 
well, 
since different islands of non-monolithic XML documents belong to different 
namespaces and thus different schemata.  For example, the MIME parser cannot 
invoke vCard applications if the vCard is embeded by the namespace mechanism.

I think this will become more and more important, and we should try to find
a solution that doesn't exclude it. On first sight, it doesn't look so 
difficult:

Define one parameter, maybe named "namespaces", that lists, comma-separated,
all the namespaces used in the document. The DOCTYPE, if present, counts as
one. The DOCTYPE, or the namespace of the root element, is listed first.
If other description mechanisms (schemas,...) are defined, the URIs used
for them can also be used.

If I'm overlooking something, please tell me.
