Covering existing situations

When we define the universal set of names and addresses, it is clearly a prerequisite that existing protocols should be covered. In some cases the protocols which have been used fro network access to information have not had a clear concept of a name or address, so the various pieces of information which are necessary for access have to be coded up into a string syntax.

Th excercise of covering existing schemes gives us some idea of what may happen when we attempt to extend the universal set to comver new naming schemes .

(up to requirements , on to extensibility )
