This is precisely my motivation: get Struts out of validation directly,
making it easier to re-use commons-validator deeper in the business
layer. Struts should be able to utilize validations, but only as a
supplement to business logic validation. In my case, my application has
multiple interfaces, one being Struts and another Axis. If I convert my
application to use commons-validator, I want to make sure I can define
validations once and reuse them within both the Struts view layer and
deeper in behind the business facade.

View based xml for validation of forms, in my view, violates the MVC
paradigm. Validation is business logic although there is a small benefit to
view based validation for performance reasons. You have to have validation
code in your business classes, so I don't understand writing a second set of
validations (even if they are only xml) which don't cover the whole range of
validation scenarios.
Additionally, since the tags don't have formatting, I have had to implement
my own tags for all of the formatted fields in order to have an interesting
user interface, i.e. lookups, numbers, phone numbers, dates, etc. which
would obviate the need for simple validations.
Of course there are exceptions, i.e. a completely view based application,
but I haven't had that experience.

I for one would never use struts validator as it is currently

Please
rethink this idea.
