Ideally, yes. But given that a) startTime and endTime predate Interval and
b) AS2 is rec track and Interval has no official standing yet, it becomes
much harder to justify.

One thing you can do, however, is (within your system), treat as:Activity
as a subclass of i:Interval and as:startTime/as:endTime as either
equivalent to or subproperties of i:lower/i:upper and you'd largely be able
to accomplish the same thing without requiring a change to AS2.

like to come up with "ASQL", the "Activity Stream Query Language", that
would allow AS users to work with any kind of AS data in a concise and
consistent fashion. to me it seems that this is much easier if there's a
common way of expressing (and reusing, when possible) concepts across AS
vocabularies, so that any data can be processed according to its AS
semantics.

something we have noticed while using AS, that using it declaratively would
be much better than just treating it as random JSON, and shared concepts
would help a great deal.
