What exactly does that identify? Is that a *feature* or a *service*?

If it's a service, it's better to identify it via disco#items or even
XEP-0215 as Maciek notes, because the service is external to the XMPP
network.

Or:

<definitions

<wsdl:definitions
      xmlns='http://schemas.xmlsoap.org/wsdl/'
      name='SomeService'
      targetNamespace='http://www.myserver.org/soap/someservice'/>

Six of one, half a dozen of the other. :)

I'm not a huge WSDL fan, but what you've described will work, I think.
