RequiredWhen or extending Constraint and _others

a few days ago I posted a Dynamic constraint with the idea of a constraining a
textfield depending on the value of a different field, e. g. a select field.
Today I needed to constrain many textfields depending on a radiogroup, as this
radiogroup decides which fields needs to be filled, so I could put a required
constraint on these fields.
This bought me to the idea of extending 'process' in constraint and _others
class (these are the base classes for al constraints) with a 'when' accessor
and the code to only run the constraint when a specific field contains a
given value (or the value is in a given range).
I would suggest the following structure:
- field: name
- value: 1
- values: [ 2, 4, 6 ]
What do you think?
