Dear VXQuery-ers,
I have added a new class with constants called ValueTag that captures the tag values to use for all data types. This is a change from using BuiltinTypeConstants to represent the tags.
ValueTag reuses the constants from BuiltinTypeConstants for tags representing builtin types and it adds tag values for more datatypes such as sequences and the various types of nodes.
I have also changed all existing code to use ValueTag values where appropriate. Henceforth, please use ValueTag in new code to reference tag values for data.
Thanks, Vinayak
