Sandy Gao at IBM has looked at the reasons
for moving to schema 1.1 and concluded that DFDL should move.
Grounds:
- Weakened wildcard support - there
is less ambiguity in 1.1 because an optional element x followed by a wildcard
will match x, instead of giving a UPA error - this will enable DFDL to
model more formats
- Relaxation of <xs:all> means
that it is suitable for DFDL use - this will allow us to drop the dfdl:unordered
property
- In Schema 1.0, annotations are lost
on particles, but they are needed by DFDL. Schema 1.1 captures all annotations.
