Current Expert manual, contains in Table 6.1 this unlikely entry, with boldface added by me to indicate the oddities:
Col 1: Queries
Col 2: The cell immediately to the right can contain global declarations which Drools supports.
This is a
type, followed by a query name. (if multiple queries are needed, comma separate them)
Col 3: Optional
I have no idea how to fix it.
