This schema was originally developed by The MITRE Corporation. The Data Marking Schema implementation is maintained by The MITRE Corporation and developed by the open STIX Community. For more information, including how to get involved in the effort and how to submit change requests, please visit the STIX website at http://stix.mitre.org.
The TLPMarkingStructureType is an implementation of the data marking schema that allows for a TLP Designation to be attached to an identified XML structure. Information about TLP is available here: http://www.us-cert.gov/tlp.
Nodes may be marked by multiple TLP Marking statements. When this occurs, the node should be considered marked at the most restrictive TLP Marking of all TLP Markings that were applied to it. For example, if a node is marked both GREEN and AMBER, the node should be considered AMBER.
This field contains a reference to an authoritative source on the marking model to be applied within this Marking_Structure.
