Yes, that's probably the reason even though I was starting to think that
it could meet a -specific yet non null- need.

And I think that it was doing well in this respect!

Yes, as you said, the need that was met by AS was not obvious and
furthermore it wasn't meeting the expectations set by its name.

From the name, the first thought was that it was a way to expose schema
stuff including PSVI like annotation while it turned out to be kind of
hiding schemas as implementation details and were a sort of black box to
which applications could ask if a modification made to a document was
valid or not.

I am still thinking that there is a need for this -even if it solves
neither the PSVI issues nor the need for abstracting the schemas- and
that it's a good way (if not the only one) to be schema agnostic. Maybe
the name was just bad and it should have been called "validation query
interface" of something like that!

Did you know it? Python has now a Relax NG (partial) implementation.
