I don't have depth knowledge in Diameter but If I understood your question then find my response a below:
- When a AVP is defined, it may be defined as a mandatory, vendor-specific. If it is defined as mandatory, in that case Diameter Agent such as proxy server should know about the AVP. If it is an optional then there is no need to know about the AVP at Diameter Agents.
- Your other question is when a particular AVP considered as mandatory and when as an optional. It is totally depends on the application requirement. An AVP that is taken as a mandatory AVP for a application, it can be considered as an optional AVP for other application.

Please find the description of the problem:

Does Proxy agent validate presence of any mandatory or optional AVP when it receives a message from a diamter client (PCEF) before forwarding it to diameter server (PCRF) ?

Diameter:Difference between Vendor-Id presents as an independent AVP and within the Vendor-Specific-Application-ID AVP ?

I saw Capabilities-Exchange-Request and Capabilities-Exchange-Answer messages. In CER message there are two places where Vendor-Id AVP is present, one as an independent AVP and the other one as part of Vendor-Specific-Application-Id AVP. If both of them are present in request message then both will be having same value or can hold different values.
