Pulling out this particular question to see if others have an opinion on 
this.

Should we change 6087bis to reduce it reliance on RFC 2119 language?

The reasoning for proposing this change is to avoid accidentally 
creating future CLRs, because tool implementations might regard the RFC 
2119 language in 6087bis as defining rules rather than just offering 
guidance.

An example change:

Before:

    Prefix values SHOULD be short, but also likely to be unique.  Prefix
    values SHOULD NOT conflict with known modules that have been
    previously published.

After:

    Prefix values should be short, but also likely to be unique.  Prefix
    values SHOULD NOT conflict with known modules that have been
    previously published.


Thanks,
Rob
