- -- generic non standard extension element
- -- the generic non - standard element contains:
- -- - an extension id to distinguish different extensions
- -- - the extension data as binary data
- -- proprietary extensions are by definition proprietary. This standard provides
- -- the means to identify these extensions
- -- within the data and to skip these data.
- -- the evaluation of these data and the unique identification of the extensions
- -- via the extension id is in the
