/**
List of all connection (JDBC) attributes by the system.
<P>
This class exists for two reasons
<Ol>
<LI> To act as the internal documentation for the attributes.
<LI> To remove the need to declare a java static field for the attributes
name in the protocol/implementation class. This reduces the footprint as
the string is final and thus can be included simply as a String constant pool entry.
</OL>
<P>
This class should not be shipped with the product.
<P>
This class has no methods, all it contains are String's which by
are public, static and final since they are declared in an interface.
