[DFDL-WG] assert and discriminator - no more before/after

[Mike Beckerle]

I am looking in the spec for guidance about the evaluation order of assert
statements.

We used to have before/after control properties, but eliminated them.

If I annotate a simpleType'd element with an assert that says { . eq 'x' },
that of necessity references the current value, so must execute after the
value has been computed.

If on the other hand I annotate a complexType element with a discriminator
that says { ../flag eq 'C1' } then this of necessity must execute before I
go after the contents because the whole point is to evalutate the
discriminator first.

Did we ever articulate exactly what the rules are here about order of
evaluation?

Thanks for reminders
