DDSXTY14 — XTypes spec is missing topic names for TypeLookupService

In section 7.6.2.3, that introduces the TypeLookupService, the datatypes used for exchanging TypeLookupRequests and TypeLookupResponse are introduced, and so are the endpoints used to exchange them.
However, what is missing is the topic names used for the topics carrying these requests and their responses. Technically you might not need the topic names to build an interoperable implementation, because the endpoints are builtin endpoints and therefore don't need to be matched, but nevertheless, the topic will need to have a name and the name might as well be part of the spec.
