CR-21: Drop use of xsi:type as determinant for unions?

Dear Asir

The W3C XML Schema Working Group has spent the last several weeks
working through the comments received from the public on the Candidate
Recommendation (CR) of the XML Schema specification.  We thank you for the
comments you made on our specification during our CR comment period, and
want to make sure you know that all comments received during the CR comment
period have been recorded in our CR issues list

Among other issues, you raised the point registered as issue CR-21: Drop use
of xsi:type as determinant for unions?

The Schema Working Group declined to adopt the proposal on the grounds that
the functionality is useful and is also well-defined. However I would note
that the Working Group did vote to change the Type derivation OK [Simple]"
constraint to read "Type allowed [Simple]" on the grounds that the members
of a union type are, as you pointed out, not derived from it.

It would be helpful to us to know whether you are satisfied with the
decision taken by the WG on this issue, or wish your dissent from the
WG's decision to be recorded for consideration by the Director of
the W3C.
