If the design (ontology) of a TM Application permits the subjects of nodes to be conferred upon them by assertions that connect these nodes to pieces of addressable information that are regarded as their "subject indicators" (the Standard Application is an example of such a TM Application), then it seems only natural to make the components of the TM Application's design document(s) that define the TM Application's assertion types and role types conveniently addressable, and to make the addresses of these components the built-in values of the appropriate SIDPs of some of the built-in nodes defined by the TM Application. In this way, the topic maps governed by the TM Application can be authoritatively self-documenting with respect to their assertion types and role types.

I am not sure what this is, but it sure isn't anything to do with
conformance.
