http://tempuri.org is injected by some tools as a namespace when no
namespace is explicitly provided. The namespace is just a scoping
mechanism -- since I own the servergeek.com domain, I can tag my types with
namespaces like:
http://schemas.servergeek.com/2004/09
because I have some implicit rights to the domain, and it's unlikely that
another developer would use my domain as part of their namespace.
You definitely do not need to post the schema at the address -- the URI in
the schema is not intended to be dereferenced from the namespace
declaration.
A somewhat dry but best-evidence document on namespaces is available at
W3.org:
