Create simpleType for date format

[ZagrebMike]

Hi,

I want to create a simpleType that will constrain an element to be a date of
the form dd/mm/yyyy.

I have this at the moment,

<xs:simpleTyp e name="newDate">
<xs:restricti on base="xs:string ">
<xs:pattern
value="((0[1-9]|1\d|2[0-9])/([0][1-9]|1[0-2])|30/(0[13-9]|1[0-2])|31/(0[13578]|1[02]))/\d\d\d\d" />
</xs:restriction>
</xs:simpleType>

but that doesn't work for leap years. Is it possible to use the date base
type. Something like:
<xs:simpleTyp e name="newDate">
<xs:restricti on base="xs:date">
??? what goes here ???
</xs:restriction>
</xs:simpleType>

Thanks!

Consider using the predefined xs:date data type. If you need a different
format when representing dates later you can always transform from
yyyy-mm-dd to your format while using the predefined type in your XML
means any schema aware software will understand values to be of the type
date.

Good thought, but I should have mentioned that this is part of a schema
defining the input in a BizTalk receive pipeline. The format is required to
check that the application generates the date in the correct format.
