[webservices] Station web service: to Network, or not to Network?

[Philip Crotwell]

Hum, ok I can see that as a bit of a pathological request. But as long
as the request sticks to real world networks, stations and time
queries, do you believe it is reasonable for a client code to assume
the single network element per network? That makes the client side a
lot easier to deal with.

thanks
Philip

This is only known to happen if you request duplicate networks, e.g. "network=_GSN,II" (the _GSN virtual network includes the II network).  We are considering how to make sure there are not duplicate <Network> elements for future releases.
