[opencms-dev] setting default expiration

[Jonathon Mar]

Hi,
Does anyone know if it is possible to set a default expiration for a
resource through the xsd file?  The idea is to default expiration for
all resources of a given type to be 1 week from creation date.  I tried
inserting the following line under the defaults node, with no success:

<default element="Expiration" value="${currenttime + 604800000}"/>

Thanks,
Jon
