Use of regular expressions

[pebran]

From time to time I have the need to make an attribute conform to a specific pattern, i.e. a mail address or a phone number.
I’ve been looking for a way to do this using OCL in a regular expression like way but that doesn’t seem feasible. Is there any canon way to do this?

Not really shure what you mean by this question but if you need some kind of assert you're free to bind a constraint to the attribute.
