Ashok,

Thanks for your responses to my inquiry about the timeInstant and Time
datatypes.  I
understand your reasoning for not allowing reduced precision for Time and we
have no
problem with that.

You mentioned that the date and time datatypes have been extensively revised
for the
next working draft.

Will you retain the ISO 8601 extended format for date and time as a valid
lexical format?
We would prefer that the ISO 8601 extended format be retained as a valid
choice for
lexical format.

Can you disclose when the next working draft of the Datatypes part of XML
Schema will
be available?

Thanks,

Ernest Nishiseki,
