If I want to validate a date field, I will put something like this in the

<field property="myDate" depends="date">
<arg0 key="Date field" resource="false"/>
<var>
<var-name>datePattern</var-name>
<var-value>MM/dd/yyyy</var-value>
</var>
</field>
So, if I want to enable 2 ways of entering a date (MM/dd/yyy and MM-dd-yyyy), how should I write in the validation.xml file?
The only two possibilities I can think of are to use the match validation
with a suitable regular expression, which will allow you to make sure the
date string is in the right format but can't easily check that it's really
a legal date, or write your own custom validation rule. The date validation
doesn't provide for specifying multiple patterns.
Actually, one other possibility: if you don't specify a pattern, Validator
will use SimpleDateFormat's default short date format rules, which might be
more flexible than you can express with a pattern; check the documentation
for SimpleDateFormat to see if that would meet your needs.
