Amelia A Lewis scripsit:
> DTD talk, the requirement is (A|B)*
That's compact RNG as well, provided A and B are defined as
A = element A { ... } and B = element B { ... } somewhere and the
ellipses are replaced with the attributes and content model.
Bare names in RNG schemas are always references to definitions;
the names themselves are meaningful only to the schema processor
and the human reader, and have nothing to do with the instance.
> The above yields (A?,B?)
That's RNG as well, with the same caveats.
