Just use the data tag standard, that is based on set data-XXXX where XXXX is the operation you want and data-XXXX-msg with the message you want.

Skip validation on a field
data-disable-validation The control with that tag, will not be validated
Only numbers accepted
data-only-numbers: The element should only have numbers ( , . - )
data-only-numbers-msg: Error message
Date format
data-date-format="dd/MM/yyyy"
data-date-format-separator="/"
data-date-format-msg: Error message
Drop down value not selected
data-select-value-different="0" //You have to select an index different than 0
`data-select-value-different-msg: Error message
IBAN format
data-iban: Validates IBAN Bank format
data-iban-msg: Error message
data-email: Validates valid email entry
