Well... I'm not going to have time to do anything here, but if I did I'd look
into moving parts of Preferences into security.  That would work well enough
for the Registry (since that has no dependencies on security), but it wouldn't
work for XML without some serious refactoring to allow an XML that supports
only local (file:) URIs in security -- that seems way too ambitious for a
project I'm not funded to work on.  These are suggestions for Oracle or any
other contributor who needs this.
