[Zope] Problem with POST and text/xml

[Jonathan (dev101)]

I need to support a third party web service (which is not within my control) 
that wants to send xml data to my zope server (Zope 2.9.2 running on Redhat 
linux).

When Zope receives a POST request with a Content-Type of text/xml it assumes 
that it is an xmlrpc call (which it is not - it is just passing xml data 
within the POST request).

Is there a way to get Zope to turn off this "xmlrpc assumption" so that my 
zope external method can process the xml data that is being passed?


Thanks,

Jonathan
