scope:

The present document defines a repository of a set of data elements and data element sets that are commonly used in the ITS applications and facilities layer messages. Each data element is defined with a set of attributes, enabling the identification of the data element in question in a number of perspectives, e.g. descriptive name, ASN.1 definition, data definition, minimum data granularity requirement, etc.

The present document focuses on the data elements being used by the Cooperative Awareness basic service [i.2] and Decentralized Environmental Notification basic service [i.3]. Further data elements are expected to be added in the future to support other application and facilities layer messages or functions.

The present document does not specify the syntax and requirements of data elements in the specific context of any message. Such syntax and requirements are specified in the corresponding message standards such as [i.2] and [i.3].
