[Nsis-imp] Unknown GIST version number

["Christian Dickmann" <mail at christian-dickmann.de>]

Hi Robert,

I got a question about an error condition: 
In GIST-09 A.1. the draft says:
"Parsing failures may be caused by unknown Version or Type values,
   inconsistent R flag setting, or a Message Length inconsistent with
   the set of objects carried.  In all cases the receiver MUST if
   possible return a "Common Header Parse Error" message
   (Appendix A.4.4.1) with the appropriate subcode, and not process the
   message further."

I wonder if an unknown version should really result in an error. 
If the node is just an intermediate node, why shouldn't it just forward
the message? Otherwise new GIST versions could be a deployment problem.
Did I miss some note in the draft about this topic, or is there any
other reasoning?

Thanks,
Christian Dickmann
