there is the 'extends' feature.. i guess that's what you're looking for.

rule "xyz"
...
end

rule "abc" extends "xyz"...
...
end

it's been recently talked about in this forum.

Hi all,

I know there are some basic ways to chain rules together, by setting flags
in consequences that are checked in the conditions of other rules...

but in a large system based on rule templates, where thousands of rules are
generated, it is not feasible to chain rules in this manner, especially when
they are chained in a somewhat arbitrary fashion
(eg. True if Rule 130 AND Rule 200 AND Rule 480 fire)

has anyone had this situation before?  would I need to execute this as a
post-processing step?  or, is there any design pattern that will allow rules
to be chained, preferably in a manageable way?

regards,
Daniel
