HOW-TO: automatically convert from variant type to xml datatype w hencreating xml instance

["DeRemer, Bob" <Bob.Deremer@wonderware.com>]

I'm using XML within a COM component and I need to be able to set the
appropriate XML datatype attribute for an element based on the datatype of
the COM VARIANT.  I'm trying to determine if there is a way to automatically
detect a VARIANT's type and return the appropriate xml dt:dt string type
name.  Does anyone know if this functionality exists in MSXML3?  I can
create a simple map that contains the information, but I'd like to use a
standard method if available.

Thanks in advance,
Bob
