Basic data from which we derive all our TypeInfo. Any j2eeType must either
have 1 or more legal parent types ( in which case it is a subType),
or must have a contained-by j2eeType (possibly null), in which case it is a
top-level type, possibly contained by something else.
<p>
Separating these two ideas enables reasonably short types that don't have to
artifically include the singletons they are logically contained in. For example,
it enables the type "X-ConfigConfig" instead of
"X-DomainRoot.X-DomainConfig.X-ConfigConfig", which is considerably longer
than (unnecessarily so).
