Re: [xrblock] WGLC - draft-ietf-xrblock-rtcp-xr-jb-02.txt

This document is in good shape, I have a couple of issues that need clarification: 

1. for all delay and water mark fields I see the following: 

>     If the measured value exceeds 0xFFFD, the value 0xFFFE SHOULD be
      reported to indicate an over-range measurement.  If the
      measurement is unavailable, the value 0xFFFF SHOULD be reported.

What are these SHOULD and not MUST? If there are exception cases please explain, if not s/SHOULD/MUST

2. in the jitter buffer maximum delay description the following sentence seems crippled: 

> In adaptive jitter buffer implementations,
      this value may dynamically.  

Something is missing here, please fix. 

Thanks and Regards,

Dan
