[Zope] How do I use Zope for XML-RPC?

I'd like to use XML-RPC to communicate between a Zope on Sun/Solaris and a Zope on Win NT. I thought I read somewhere that Zope supports XML-RPC, but I can't see how it is done. Does Zope support XML-RPC out of box, or is some assembly required? Does Zope ORB parse XML-RPC requests/responses? How does it know it's getting XML-RPC? By the Content-Type? Is there any support in Zope for a method to create XML-RPC requests and responses, or does the method have to generate XML itself? -- Thanks -- Loren
