The constraint element defines the selection of grid objects such as resources. The required type attribute defines the selection type. Supported types are:
Resource
Provision
Allocation
Accept
Start

vmhost
Repository
Constraints can also be constructed in JDL and in the Java Client SDK. A JDL constructed constraint can be used for grid search and for scheduling. A Java Client SDK constructed constraint can only be used for grid object search. For additional information, see Working with Facts and Constraints
