4.1 Procedure S"eciicatio% Pri%ci"es

The principle for specifyin the procedure loic is to specify the functional behaviour of the terminatin node eactly

and completely. ny rule that specifies the behaviour of the oriinatin node shall be possible to be verified withinformation that is visible within the system.

The followin specification principles have been applied for the procedure tet in clause =I

> The procedure tet discriminates betweenI

,) 7unctionality which shallN be eecuted

The procedure tet indicates that the receivin node shallN perform a certain function D under a certaincondition. &f the receivin node supports procedure but cannot perform functionality D re@uested in the/2F2"T messae of a 1lass , 2P- the receivin node shall respond with the messae used to reportunsuccessful outcome for this procedure- containin an appropriate cause value.

*) 7unctionality which shall- if supportedN be eecuted

The procedure tet indicates that the receivin node shall- if supported-N perform a certain function D undera certain condition. &f the receivin node supports procedure - but does not support functionality D- thereceivin node shall proceed with the eecution of the 2P- possibly informin the re@uestin node about the

not supported functionality.

> ny re@uired inclusion of an optional &2 in a response messae is eplicitly indicated in the procedure tet. &f the procedure tet does not eplicitly indicate that an optional &2 shall be included in a response messae- theoptional &2 shall not be included. 7or re@uirements on includin Criticality Dianostics &2- see clause ,+.

4.2 'orards a%d 7ac8ards o"ati&iit

The forwards and bac#wards compatibility of the protocol is assured by mechanism where all current and futuremessaes- and &2s or roups of related &2s- include &8 and criticality fields that are coded in a standard format that willnot be chaned in the future. These parts can always be decoded reardless of the standard version.
