Thanks for the clarification on the registry split. That cleared up the
confusion I had around why `forName()` worked for types but failed for
service names like `com.sun.star.frame.Desktop`.
I now understand that:
- Components (services, singletons) are handled by the ServiceManager
(cppuhelper/source/servicemanager.cxx)
Just to reiterate: the ServiceManager is about component
*implementations*...
- UNOIDL entities (types, structs, enums) are handled by the TypeManager
(cppuhelper/source/typemanager.cxx)
...while the TypeManager is about all kinds of UNOIDL entity
*descriptions*, be them types (enums, structs, exceptions, interfaces)
or non-types (modules, services, singletons).
So for the Object Browser, the data provider will query both systems:
the ServiceManager for creatable components, and the TypeManager (via
`theCoreReflection`) for types.
Appreciate the precise pointers. This helps make the data pipeline
design a lot clearer.

Data about the two different kinds of .rdb files, one for component
(i.e., service and singleton) implementations (i.e., what is
codified in
.component files) and one for UNOIDL entities (both types and non-
types;
i.e., what is codified in .idl files), are kept distinct, see
cppuhelper/source/servicemanager.cxx for the former and
cppuhelper/source/typemanager.cxx for the latter.

The css.reflection.TypeDescriptionManager service provides information
about all kinds of UNOIDL entities, both types and non-types (like
services and singletons).
