Just another idea,

build a new Validator Class within 
"Class/Domain/Validator/mydomainnameValidator.php".

Then inherit the TX_Extbase_Validation_Validator_AbtractValidator and 
overwrite (you must overwrite) the isVaid() Funktion. You can also use 
"$this->addError()" to get error flash messages.
