Currently users cannot configure date-effective/date-expires for rules when they use SpreadSheet. (It's possible in case of Guided Decision Table Editor)

The request is being able to specify date-effective/date-expires like other attributes ( http://docs.jboss.org/drools/release/5.5.0.Final/drools-expert-docs/html_single/#d0e1309 "Table 2.2. Rule attribute entries in the Rule Set area" )
