Is is possible to use multiple 'mask' validators that apply different
expressions?
For instance, in addition to checking that a string contains only a-z or A-Z
characters, you might want to validate the string length. It's possible to
use an expression that combines the types of validation (e.g.
^[a-zA-Z0-9]{,16}$), but then it's not possible to use an error message that
is specific to whether the validation failed due to the character content or
the length.

This is what you were asking about though? Everything
makes sense now?
