With a regex you could use something like this
[1,2,4-9][0-9]?"-"[1-9][0-2]?-"[0-9]{4} |
[3] ( [0]"-"[1-9][02]?"-"[0-9] {4}) |
([1]? "-" [1-9][0-2] "-" [0-9]{4} )
In Schematron, you could express the constraint using something like this:
<sch:rule context="thing[@date]">
<sch:let name="day" value="substring( @date, 1, 2)" />
<sch:let name="month" value="substring( @date, 3, 2" />
<sch:assert test="not( $month = 2 and $day= 30)">
The date value should not be February 30
</sch:assert>
</sch:rule>
