How to reuse field validators?

[Griffith, Michael *]

Hello all, 
 
I am not clear on how to reuse a field validator that doesn't share a
common package or action/alias.  I have package
 
...struts.admin/
...struts/application/
 
with namespaces /admin and /application respectively.  I have a model
object with a validator <modelClass>-validator.xml in the /application
package that I need to reuse in the admin package.  What's the best way
to reuse the validator without repeating it?

Thanks in Advance, 

MG
