Re: [bv-dev] Legal to validate constraints more than once?

execute all [...] validations [...] matching the targeted group unless the given validation constraint has already been processed during this validation routine for a given navigation path [...] as part of a previous group match

Note that this implies that a given validation constraint will not be processed more than once per validation.
