Hi John

That is great!
Yes I agree!

Best Regards,
Georgios

Hi All,

The current text states:

5.1.3 Modularity  

   A modular design allows for more lightweight implementations, if 
   fewer features are needed. Mutually exclusive solutions are 
   supported. Examples for modularity: 

   - Work over any kind of network (narrowband / broadband, error-prone 
   / reliable...) - This implies low bandwidth signaling and redundant 
   information must be supported if necessary.  

   - Uni- and bi-directional reservations are possible 

   - Extensible in the future with different add-ons for certain 
   environments or scenarios  

If I understand Georgios' request, he would like an addtional bullet,
which I would phrase:

   - Protocol layering, where appropriate.

Is that OK?

John
