No, there are two things you have to add:

One is self_get_js(), whose parameter is $ndx_array - an array of 
element numbers within the form. You then write the validation in 
Javascript. Take a look at of_text for an example, just notice what 
it does for non-multiple text fields.

The other is self_validate(), whose parameter is the value to 
validate. This function is called on the server side (in case the 
user disabled javascript). If it returns false, then the validation 
SUCCEEDED. Otherwise, it must return the error message (Like 
$this->valid_e or $this->length_e, depending on whether you are 
checking regexp or length).

Again, you may take a look at of_text for an example what to do. It 
may be that for regexps you'll have to change modifiers to deal with 
the fact that multiple lines are allowed.
