A sequence of one or more <access_specification> elements make up an <access_specifications> element. In the Messaging Toolkit, the <access_specification> element includes a <destination> element.
Each <access_specification> element has a single attribute, name. The name value can be specified in the access parameter of a Messaging Toolkit operator.
Note: The MQTTSource and MQTTSink operators do not support the <access_specification> element.
