[rules-users] Question on "or" rule syntax

If I use this syntax for an "or" with binding: pensioner : (or Person( sex == "f", age > 60 ) Person( sex == "m", age > 65 ) ) I get a compile error. Is this syntax supported? I can successfully use this syntax: (or pensioner : Person( sex == "f", age > 60 ) pensioner : Person( sex == "m", age > 65 ) ) which works okay but I was wondering if the documentation or implementation is incorrect.
