[to this thread in general, not anyone in particular]
We have done this work over 2 years in the working group. It has been presented multiple times with multiple revisions etc. We have arrived at a solution that works, and has cleared WG LC, and IETF LC.
We have a process we need to follow it. Yes if something is truly broken and has somehow escaped all the previous checks it needs to be addressed. But general musings about how one might do things a little different or a little better are not appropriate at this very late stage, otherwise we never get anything done.
Not getting things done in a timely manner has been a problem highlighted at least with the work in netmod if not the IETF in general, and has been the subject during many meetings at this point, on how to fix it. Endless revisionism is one of the major factors identified as a problem.
Can we please restrict discussions on this document to editorial/minor corrections or changes that have to be made b/c otherwise the solution will not work?
Thanks, Chris.
In that case, why not make it so the tags are actually valid URIs, similar to XML namespaces?

The intent was to not put the MUST on users. As the final arbiters of tags, users should be free to do whatever they want and not have implementations or standards superfluously block them from doing so. How about we carry the SHOULD into the typedef in the YANG model as well? That seems reasonable to me, i.e.,
typedef tag {
type string {
length "1..max";
pattern '[a-zA-Z_][a-zA-Z0-9\-_]*:[\S ]+';
}
description
"A tag is a type 'string' value that does not include carriage
return, newline or tab characters. It SHOULD begin with a
standard prefix.";
I strongly agree that a prefix SHOULD be present, not MUST be present. I also think the 3 standard prefixes will be insufficient over time. (Having every organization on the planet except IETF share the prefix "vendor:" seems a bit short-sighted)

How about:
"Tags of any kind can be assigned and removed by the user using normal
configuration mechanisms. In order to remove a tag from the
operational datastore the user adds a matching =masked-tag= entry for
a given module."

Covered earlier (BCP).

Added.
