When a user deposits an item via SWORD by using METSRights metadata  within  the mets file to transfer the embargo period, none resource policy type is set by the METSRightsCrosswalk class.  This results to the Embargo Date not being displayed to the admin while editing the metadata of such workflowitem in the Upload File(s) (while changing the Embargo Settings of a file) and Verify Submission step.

The provided policies are added by users, therefor the resource policy type: TYPE_CUSTOM should be added.
