CMPWG 10/27/2016:

Is there a situation that a GDS would reject RegisterApplication?

For example, can I register an application where the applicationUri already exists?

The current text says "... to register a new Application"; does "new" mean a unique applicationUri? or does it mean that any field within the ApplicationRecordDataType structure is different?

Are there reasons that justify the existence of multiple records for a single application? (we couldn't think of one)

We think additional guidance is needed:

• Perhaps add text like "Applications should check the GDS first, to see if they are already registered before calling RegisterServer."
• Perhaps also add text like "Applications that have changed, perhaps capabilities have been added/removed etc., should call UpdateApplication to update the GDS instead of RegisterApplication."

This is made a little more confusing with the following text found in 6.2.4 FindApplications:

"... however, system configuration errors can create situations where the GDS has multiple entries for a single ApplicationUri."
