##Source: IBM (Stephen A. White, wstephe@us.ibm.com)
##Original Issue: http://www.osoa.org/jira/browse/BPMN-411
##Original Info: (Severity: Critical - Nature: Enhancement)

The state of a Data Object should be considered as a Performance Constrainst for an Activity Changing from the Ready to Active state.

If a Data Object is not in the state defined as an input (e.g., "Approved"), then the InputSet should not yet be considered "available."
