[Simple] RFC 4662 Clarification

["Eric Tremblay" <eric.m.tremblay at gmail.com>]

Hi,

I would like to clarify the meaning of the "fullstate" attribute in RFC 4662 when it is set to true.

Basically the question is the following:
If I am supporting pidf-diff and subscribe to an RLS, can I assume that whenever I receive an RLMI with fullstate=true that for all "active instances" of this RLMI I will have full PIDF information (either "application/pidf+xml" or "application/pidf-diff+xml" with <pidf-full> element)? 
Here "active instances" are <instance> childrens of  <resource> with the state attribute set to "active"

4662 specifies that when fullstate is set to true, all "state" must be removed and rebuilt from the information available in the RLMI. Unless I am confused by "state" (I assume the state being transported by the RLMI, PIDF as an example, as well as the RLMI list of resources), this only then works if full state information is transmitted instead of partial state info. The misleading part comes in section 4.6, where it is stated that if full state is specified, it applies only to the RLMI document in which it occurs. I would have expected this to trickle down to "embedded" RLMI as well as any other type of payload. Now because RLMI with fullstate is allowed to transport "partial" RLMI, I am wondering if my understanding about the other type of payloads is right. 

As an example, if we take the figure on page 16 (copied for your convenience), I would have expected Part D (and Part C, E and F) to contain full state information if Part A specified full state information.
