[CESG] RE: "Recommended Standard" or "Standard"

Same for CNES : CCSDS standards are usually made directly applicable to projects (with an applicability matrix if needed). As Chris wrote, we use to rely on ESA-PSS standards which actually reformulated/repackaged CCSDS recommendations. It is no more the case. The term "recommended" is both historical and maybe still political because it implies a lower level of commitment of CCSDS member agencies to actually apply those standards to their projects.

Chaps this goes back to the days where esa was preparing its own standard based on ccsds but released under our pss series. These days have gone and where possible we apply ccsds recs as is. In this respect no problem to change to "standard" rather than recommended.

	You're right, Tom.  My memory was that we required "Recommended Standard" because simply "Standard" carried the weight of a "Required" compliance to the standard which invoked the more political requirements of international agreements (State department approval, etc.).  
	I think I should handle that with a direct dialogue with Martin.  
	If someone has a historical track record that would help substantiate the theory above, I would appreciate hearing from you.  I will address Martin next week.

	 From the discussion this morning is appears that we may be very near 
	to being able to publish the document, but there remains one 
	problematic comment from DLR that needs an explicit response from the CMC:
	"DLR proposes to change recommended standards into standards, because 
	DLR cannot see any additional value from the word recommended and in 
	the end on the ISO level  we will have a standard."
	I believe a CMC poll is necessary to get consensus on the proposed 
	change, since at one time there was strong objection from certain 
	agencies to referring to CCSDS Blue Books as actual standards.
	I should point out that, as a practical matter, changing the term 
	would not be a simple thing, since it would involve changing a 
	massive number of templates, etc., in which the term is hard 
	coded.  On the other hand I personally feel that, if we can get 
	everyone to agree, it would be a positive change.
