Provisioning Framework - inability to provision custom attributes to bushy stems

In Grouper 2.2.2 and the old Grouper PSP software, it was possible to provision custom attributes on bushy stems.  For example, it was possible to set the displayName of a stem separately from the ou attribute in LDAP, along with setting other custom attributes (e.g. course codes or owning departments).  We currently use these custom attributes for managing course groups in our VLE/LMS system.  However, in the new Provisioning Framework and PSPNG, bushy stems are created as needed, but only with the objectClass and ou/RDN attributes.  This means that if other attributes are required by the schema, the stem addition will fail.

It would be useful if the new Provisioning Framework were expanded to allow attribute provisioning to stem objects in LDAP to allow for the addition of non-RDN/non-objectClass attributes to avoid such issues, and avoid the need for a custom reconciliation process to add the missing custom attributes.
