The determination of the ontological basis of a TM Application, how that ontological basis is bootstrapped, and how self-documenting (in terms of the topic map) the ontology is, are all in the realm of TM Application design. For example, a TM Application may be designed in such a way that all of its assertion types are represented by built-in nodes. Alternatively, a TM Application may be designed in such a way that only enough "bootstrap" assertion types (with built-in SIDPs) are required to be present to allow external definitions of all other assertion types to be used to confer the SIDP values of such assertion type subjects upon the nodes that represent them.

This is all TM Application stuff and should be reported in that
location.
