You missed the point. When you need to change the definition of the
datatype, you only need to change it once in the type definition, you
don't need to change it all over the places in the web document.

You are assuming that you only need to go across the room, best of
luck when you need go on a freeway or over the desert.

You can not see benefit of user defined datatype? What can I say.

A book example of union datatype is that you have shoe sizes that can
be in inches, as well as S, M, L, XL.

What is UI of a datatype that has pattern in it? Does that mean that
we should not have patter? For datatype where no obvious UI makes
sense you just have a text field whose data is verified to conform the
datatype.
