looked through the Drools documentation, and haven't been able to find out
what it does.
It's deprecated syntax for a predicate constraint, from drools 3.0.x.
Just use an embedded eval(....) now.

It appears in the autocomplete of my IDE for Drools, and I've
seen it in an
example in the JBoss Seam documentation, but am unable to tell what it does:
rule InsertMemberBlog
no-loop
activation-group "permissions"
when
principal: Principal()
memberBlog: MemberBlog(member : member ->
(member.getUsername().equals(principal.getName())))
check: PermissionCheck(target == memberBlog, action == "insert", granted
== false)
then
check.grant();
end;
