Detailed Description

<<spec>> Stores (name, value) pairs that can be used to determine access permissions.

The dds::core::policy::DataTag can be used to associate a set of tags in the form of (name, value) pairs with a dds::sub::DataReader or dds::pub::DataWriter. This is similar to the rti::core::policy::Property, except you cannot select whether or not a particular pair should be propagated (included in the built-in topic). Data tags are always propagated. The Access Control plugin may use the tags to determine publish and subscribe permissions.
