-- ECallMessage is the top level information element

-- Elements:

-- id: MSD format version set to 1 to discriminate from later

-- MSD formats (CurrentId can be used).

-- Later versions to be backwards compatible with existing

-- versions.

-- Systems receiving an MSD shall support all standardised MSD

-- versions, which are each uniquely identified using

-- an MSD format version parameter which shall always be

-- contained in the first byte of all[current and future]

-- MSD versions.

-- The uniqueness of each specific relative identifier

-- These identifiers are all relative to a specific root

-- The root of all eCall relative oid's must be the same.

-- Note that not only the syntax of the data structure should

-- be referenced via this identifier but also the symantic

-- meaning of the content so that it can be usefully applied.

-- data:Transparent optional additional data,

-- according to the format referenced by the oid

-- The user must ensure that the size of this element

-- is restricted to ensure that the total ECallMessage is

-- small enough for the relevant transmission medium.

-- Several of the elements above are "extendable"

-- at the end of the list

-- Example: numberOfPassengers,

-- ...,

-- newMsdParameter1 TYPE1,

-- newMsdParameter2 TYPE2
