ows_PermMask in SharePoint WebServices

Question

Lists.GetListItems form the Lists Web Service returns a ows_PermMask attribute (16 character hexadecimal) for each list item.

Anyone know how this attribute maps to the user's permissions or where the meaning of this attribute is documented?

It is just a built in field containing the permissions required:
