Hi Joel,

I understand that introducing "WG engagement" is a novel approach to focus the 
Working Group's efforts on documents actively being developed by engaged 
editors and contributors. It's a reasonable idea to give this a try and observe 
how the experiment unfolds.

However, I believe a charter must be precise and accurate in defining what is 
within or outside its scope. Without a formal understanding of what "WG 
engagement" entails, it remains unclear what the Working Group agrees to work 
on or exclude. I have no objection if the group uses a WG engagement metric to 
decide whether to adopt a draft. Nevertheless, I'm not convinced that ambiguous 
requirements should be part of a charter, especially when they are not clearly 
understood from the charter text itself.

I find that descriptions on a wiki are volatile, with limited restrictions and 
change control mechanisms, whereas charters undergo a formal change control 
process. Not having a clear understanding of what "WG engagement" exactly means 
by reading the charter makes me uneasy about who decides what is in or out of 
scope.

There appear to be three aspects to your concern about engagement.

First, in order to be clear about what we mean, it is simply too long and 
detailed to include in the charter.

Second, we have circulated to the WG and once the charter is approved will put 
in the WG wiki a detailed description of what we mean by engagement and how it 
relates to the various steps in WG policy.

Third, and probably most important, the text about WG engagement is not 
intended in any way to expand the remit of the WG.  Rather, it is a further 
limitation within the requirement that work be in-charter for the working group.

Yours,

Joel

Thanks.
