---------------------------------------

The code has been committed.  Doc changes and release note updates are pending - would like to see if there will be anything else based upon TEIID-5798 to account for.

> We have a long standing issue with the permission system mostly due to the initial api design - we only pass fully qualified names to the policy decider in the from of schema.table.  If the table name contains '.' the policy decider simplistically walks up each segment - which effectively introduces inappropriate checks.
> For example if we have:
> view "a.b" and view "a", when we check permissions for "a.b" we'll first check for the a.b resource, then the a resource - which is not appropriate.  This behavior in part was likely initially due to multi-schema import scenarios, such that the imported table names would be qualified by source schema name.  Then you could add permissions against that partially qualified name teiidSchema.sourceSchema.  That will no longer be possible if we implement TEIID-5840
