[rules-users] sharing functions across namespaces

Anyone know of an elegant solution to sharing functions across packages? As an example, given a single DRL containing all of functions: package com.rules and two rules files who both use those functions, yet live in separate namespaces: package com.rules.setOne package com.rules.setTwo Can both namespaces utilize the functions without changing all of my rules files to the namespace com.rules? If worth noting, only one of the namespaces will be present in the kbase at a time. Thanks, Jeremy
