Change definition of the any field for the Extension type.
Several developers from various companies have emailed me about the requirement
that the extensions come from a non-WSRP namespace. The question centers
on how to then reuse the types defined within the WSRP namespace. I suggest
adding the following sentence:

Document: Spec 
Section: 5.1.1

New Text: While the element definitions for these extensions
are required to be in a namespace other than WSRP, the reuse of the types
defined within the WSRP namespace by those definitions is encouraged as
this increases the likelihood of the receiving partner being able to deserialize
the extension in a useful manner.
