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.
