Subject: [ANCP] Mandatory vs. optional TLVs

In the ANCP protocol document, I have put at the beginning of each capability 
description a list of the protocol elements an implementation MUST support to be 
able to advertise that capability. However, the existing text indicates for each 
individual TLV whether it is mandatory or optional. What does "optional" mean here?
  -- mandatory to implement, optional to include in any given message instance?
  -- optional to implement?
