I'm also working on some generic definitions that you may want to share with the review team (so "M" and "O" mean the same thing to everyone):<br>
<br>
<b>optional</b>. Not necessary for interoperability.<br>
<br>
Optional capabilities can be excluded from an implementation (and made unavailable to users) without affecting the essential operation of the implementation.<br>
<br>
Implementation options should not be confused with user options; i.e., there may be any number of features which a user can elect not to use but which need to be available in an implementation.<br>
<br>
Also, whether a capability is optional may depend on whether the implementation is sending, receiving, or acting as a relay. A capability that a transmitter can do without might nevertheless be required at a receiver to accommodate transmitters that implement
the capability.<br>
<br>
<b>mandatory</b>. Required for interoperability.<br>
<br>
Mandatory capabilities are all capabilities that need to be available for use for normal operation of an implementation, regardless of whether a user can elect not to use them.<br>
<br>
<b>conditional</b>. Mandatory or optional depending on specified conditions.<br>
<br>
<br>

The attached PICS annex reflects your changes. I don't really know who makes up the review team, so I think you should distribute it. If you know of individuals who were involved in the protocol testing it would be helpful to include them.<br>
<br>
You might also communicate the following PICS general principles to the review team:<br>
<br>
- A PICS proforma is supposed to be limited to static conformance requirements, so any items referencing dynamic protocol behavior should be omitted.<br>
<br>
- A PICS proforma is supposed to list ALL optional capabilities but only MAJOR mandatory capabilities. Reviewers should determine whether lists of all-mandatory capabilities subordinate to a higher-level mandatory capability can be reduced to show simply the
higher-level capability.<br>
<br>
- Items that reference implementation-internal behavior that does not affect interoperability should not be included.<br>
<br>
I'm still cross checking to make sure all the changes have been made to the specification itself. I'll send it for WG signoff when I'm done.<br>

<br>
I went through the proposed PICS for the Data Link Layer and made some<br>
changes some of which we spoke about over the phone and some new ones.<br>
Please use this content to send out to the review team. No doubt we will<br>
quibble over some Os and Ms, but for the most part, I feel pretty secure<br>
about them.<br>
<br>
Also note:<br>
<br>
1. Like we talked about, add a note about DLL = Data Link Layer in the<br>
item mneumonic<br>
<br>
2. I found an error in the Prox-1 spec. It is in the MIB annex (now annex<br>
C ?). Remote_PCID is Mandatory (it says Optional in the spec, which needs<br>
to be corrected.)<br>
<br>
Thanks!<br>
