Detailed Description

A key/value pair that describes an attribute of a Feature.

Converts implicitly to std::pair<K,V>.

Warning: A Tag object is a lightweight wrapper around a pointer to a Feature's tag data, contained in a FeatureStore. It becomes invalid once that FeatureStore is closed. To use a Feature's keys and values beyond the lifetime of the FeatureStore, convert them to std::string, which allocates copies.
