Represents the metadata schema for an item. This includes how to identify an item and its version information, and how change units are defined.

typedef struct _ITEM_METADATA_SCHEMA
{
  SIMPLE_SYNC_FIELD_DEFINITION *pCustomFields;
  ULONG cCustomFields;
  IDENTITY_RULE *pIdentityRules;
  ULONG cIdentityRules;
  CHANGE_UNIT_VERSION_RULE *pChangeUnitVersionRules; 
  ULONG cChangeUnitVersionRules;
} ITEM_METADATA_SCHEMA;
