"JAXB does it" isn't an argument that carries a great deal of weight
with me, as you know.

I doubt you'll find much.  If you're going to go arbitrary precision
Big[Integer|Decimal] is what you end up with, so why reinvent the wheel?

For our code, above xmltooling, what we probably should consider is
whether we should just unmarshall that data in to java.lang.String.  I'm
not aware of any place where there would be the assumption that you
could perform arithmetic operations on the data.
