Oracle tablespace clause in index/constraint DDL

[Tim]

I'm generating DDL for an Oracle 10g database and want to be able to define the tablespace and storage clauses for unique index and primary key contraints within my model.  I've done this at the table level using tagged values, but cannot seem to do it for primary keys or indexes even though the help suggests this is possible - I seem to be able to add the tagged values but these do not appear in the generated DDL.
Any suggestions?
