[cddlm] Doubt about "Resolve" operation on System

[Ayla Debora Dantas de Souza - Projeto Ourgrid]

Hello all,

we are implementing the "Resolve" operation from the System and we had 
the following doubts:
1. What should happen if in the "path" we specify a prefix, but in the 
CDL being queried that prefix is not defined?
As far as we know, XPath does not support queries using namespaces, only 
prefixes. Considering this, the prefix used must be defined on the XML 
being queried. Are we right?

2. What must happen when the "path" passed for the "Resolve" does not 
present a prefix?
We think that in this case, a response representing an emply result 
should be returned to the user. Ok?

Thanks,

Ourgrid team.
