While rewriting what is now section 5.10, Domain Specific Languages, I've come across several references to DSL and DSLR editors in the IDE and BRMS. Some of these paragraphs are misplaced, and/or rather incoherent, and things might be missing: thus, they cannot remain as they are. I can commit the revised section and expect s.o. else to write an empty subsection referring to IDE & BRMS. Or I can incorporate an improved writeup of whatever of IDE/BRMS should be documented as a part of the "language definition" for DSL, provided s.o. sends me this text. Or I can refer readers to other parts of the documentation (which ones?) where these topics are fully covered. Or...? Please advise. Cheers -W
