	If none of the protocols is patent free, why we do not make the 
following
	choice:
	The requirement and standard do not specify any algorithm, leave it as a
	black-box... And the standard should be general enough so that most of 
the
	algorithms could be implemented (each algorithm should have a unique

PDM has not been patented. This doesn't mean of course that it is
absolutely certain someone doesn't have a patent that might cover some
aspects of it,
but PDM itself is not patented. So we don't need a statement from
our organizations that it will be licensed on reasonable terms, or
free terms provided that people who use it grant license to any
of their technology, ... It's simply not patented.

It would be nice to at least come up with a single MUST implement, as
well as a bunch of other choices, should the MUST alg wind up cryptographically
broken or with someone showing they have a patent on arithmetic which
covers it.
