The XML fact element defines a fact to be stored in the grid object’s fact namespace. The name, type and value of the fact are specified as attributes. For list or array fact types, the element tag defines list or array members. For dictionary fact types, the dict tag defines dictionary members.
See the example, /allTypes.policy. This example policy has an XML representation for all the fact types.
Facts can also be created and modified in JDL and in the Java Client SDK.
