The name of example 3.5 right now is "Request for Quotation". That is the only place in the spec that those words are used. I think this should either be changed to "RFQ" or "Request For Quote" (which appears three times).
(Overall, the fact that "RFQ" means "request for quote" is not especially clear and maybe we should fix that up as well?)
