+ * The identityref type is used to reference an existing identity.
+ *
+ *  The identityref's base Statement :
+ *       The "base" statement, which is a substatement to the "type"
+ *  statement, MUST be present if the type is "identityref".  The
+ *  argument is the name of an identity, as defined by an "identity"
+ *  statement.  If a prefix is present on the identity name, it refers to
+ *  an identity defined in the module that was imported with that prefix.
+ *  Otherwise, an identity with the matching name MUST be defined in the
+ *  current module or an included submodule.
+ *  Valid values for an identityref are any identities derived from the
+ *  identityref's base identity.  On a particular server, the valid
+ *  values are further restricted to the set of identities defined in the
+ *  modules supported by the server.
