Note that this is to be set on the server side only, and restricts the
server to accepting connections from clients only with the specified
security mechanism.

Also, it might be nice to have a reference to these server properties
in the tuning guide where all the other properties are mentioned so
that there's a complete listing of the properties in one place.

Note that these two are for specifying the security mechanism for the
connection client side.

I'm not clear on the reason for the lack of documentation, but I agree
it is unfortunate. I've opened DERBY-2361 for adding documentation for
the connection URLs. See also DERBY-963 for changing the client to use
text names instead of numbers to match (1) and (2).
