Re: AW: Re: Simple Label=RevisionID Discussion

Yes, you have. Perhaps I should have been more clear.

The *summary* in the first part of my email was intended to make the
point that it would be useful to add these restrictions to the proposal
since it further defines the intended scope of the solution, thereby
avoiding feature drift.

The second point I tried to make was that there is the suggestion of
two discrete groups of people: simple users that would use labels and
advanced users that would use tags. That seems to be a significant
simplification of the world at large. Furthermore upgrade issues will
exist.

I think these three issues wil have to be dealt with *in the proposal*
if the ultimate goal is to write a proposal that would convince the
existing Subversion developers.

With regards,
Gerco (only trying to be constructive).
