Re: email straw poll: literal semantics proposals

B: 0

It does not provide for datatyping, only for a weak form
of lexical constraint that has nothing to do with the
expression of datatype values. Thus, it does not meet our 
charter to provide a solution for datatyping that is compatible
with XML Schema datatypes.

C: 1

D: 2

F: 5
