Is this use case as generic as I think it is?

For example, if the data type is XSD#dateTime and I was
looking for *2*, I would be matching both lexical forms


I am not sure this is a necessary use case.
I would agree regular expressions are useful for some
datatypes such as strings but not for all of them such as
