[rules-users] Tags on Facts (propertyChange Support for example) in Guvnor

Have been helped about declaring attributes of facts for things such as propertyChangeSupport. However, when I import a DRL file that has such attributes into Guvnor, there does not appear to be any evidence that anything happens. The source code returned from Guvnor does not include the attributes. Does Guvnor know how to handle metadata that are declared in DRL files? Thanks. - Mike
