Much better

Well, okay. Bear in mind then, that you can never publish a second
edition or a new version of this specification that has any deprecated
or obsolete features, as these would contradict the one constraint that
you have on extending the specification. Also bear in mind that any
third party can conformantly claim to have published version 2 of

However, your addition of a comments field on the pro-forma goes a long
way to allowing specifications to talk about what their extensibility
mechanism is, so overall i think this is fine.

The main point in this part of the comment was to test whether the
extensibility mechanism requirement was truly universal.

Would a comment "We have no extensibility mechanism because we think they
are bad" count as an extensibility mechanism in terms of SpecGL

Okay (although I think first versions of specifications can sometimes
