[DFDL-WG] whitespace in DFDL annotations: right now regex is xs:string, expression is xs:token

[Mike Beckerle]

This came up on the call. The schemas I have for DFDL annotations have
DFDLRegularExpression as an xs:string, and DFDLExpression as an xs:token. I
have no clue what a union of these types behaves like. But we have a union
called DFDLExpressionOrPatternOrNothing which is a 3-way union of
DFDLExpression, DFDLRegularExpression, and EmptyString (which is also
derived from xs:string but has length facet of 0 as well.
