How do I modify rules to ignore tagged LCRs?

I have discovered that using dbms_streams.set_tag has no effect and that the reason is (I think) that my rules (specifically capture rules) 

do not include reference to "is_tag_null" condition.  How do I fix it?

DB is 11.2.0.2, and all rules were created by using dbms_streams_adm.maintain_tables.  

In discussions I see reference to using parameter "include_tagged_lcr" (in setup or "alter_rule") but I don't see any such parameter.

I also see reference to replacing rule_condition with text that has been altered to include:"and (:ddl.is_null_tag() = ”Y”)" 

but this seems pretty drastic.  I thought ignoring LCRs with tags set was default behavior.
