Detailed Description

State for the XML parser.

Several members of this struct are used to cache traffic data model objects until they can be incorporated in a message.

All struct traffic_point members are reset to NULL when the location member is set. Likewise, the si member is reset to NULL when a new event is added. The location and events members are reset to NULL when a message is created.
