Sounds like a plan. One thing though: the RE "[+|-]?\d+(.\d+)?" should be extended to allow for currency symbols and names in front or after the monetary value.

isn't this better handled by a separate method/attribute?

(otherwise, I fear that we'll end up adding all possible currency notations to the abstract type. but maybe there is a standard for this, somewhere?)
