[DAS] dsn

[David James Sherman]

Except that the entry points /define/ a coordinate system, not a
interesting (bookmarked) position on a coordinate system. They are the
origin of your number line. Feature coordinates on different number
lines---for example, on different chromosomes---are incomparable.

Of course, the starting point for an exploration on the server need
not be the list of entry points. It could be a server-published list
of interesting features, which could be entry points (number line
origins), arms, golden path contigs, etc. according to server policy.

I believe that the current protocol doesn't distinguish between the
two roles played by entry points (coord. system and starting point).
