ISO/PAS 17684:2003-Transport information and control systems - In-vehicular navigation systems - ITS message set translator to ASN.1 format definitions.
This Publicly Available Specification specifies a method that can be used to define navigation message sets in tabular form with a subsequent translation into a corresponding ASN.1 description. An intermediate language called Descriptor Normal Form (DNF), which is a subset of ASN.1, is specified and used as an intermediate description between a tabular form and its ASN.1 description.
A tabular-form message-set description language called Message Set Tabular Form (MSTF) is included as an example of a tabular form definition.
