TBH, I'd build a custom validator for this. The date validator as it
currently stands checks to ensure the provided date is valid -- and as
such needs the full date. What you're describing is a very specific
strategy that allows for multiple specifications, dependent on locale.
Within your validator, I'd determine what segments I had, and then add
data to them in order to validate them against Zend_Validate_Date -- so,
for instance, if you got just the year, add month 01 and day 01, and
validate; if you go the year and month, add day 01 and validate;
otherwise, validate the entire date.
