XML-RPC is not very helpful here.  As usual, its extreme simplicity is
both a blessing and a curse.
The specification, http://www.xmlrpc.com/spec , specifies POST with
content-type of text/xml, and that's all; so you really can't
distinguish XML-RPC from any other xml POST just from the header.

I suppose the publisher could cheat a bit and look in the body for the
required <methodCall> element.  If missing, it can't be XML-RPC.

It would be more reliable if some configuration was required to specify
when XMLRPC is expected, and when not. But that would break Zope's
longstanding promise that XMLRPC is supported "for free", always,
