Tag properties are attached to most objects in DicomObjects.  The values are not used by the associated object, and are available for user use.  A special case is the DicomConnection object, where Tag is included in the ActionComplete event procedure, assisting  identification of necessary features of the connection, such as pending database operations etc.  In this use, the value of Tag is stored at the time an operation is initiated, and it is this stored value which is passed to ActionComplete, simplifying the task of tracking which operations have happened.

The TagObject property holds another object, typically a DicomLabels collection, and this can be useful when arranging DicomLabel objects into groups.
