Dear all,
trust me on this, Paul is exactly right.

Dale,
I agree that they have been _treated_ as normative, but they are not _in fact_ normative. An IG simply _records defects and corrections_ in one or more Recommendations while a Corrigendum _corrects_ a particular Recommendation. According to the ITU-T, the only way to correct a Recommendation is to issue a Corrigendum or revise the Recommendation. An IG is therefore a working document of which implementors are prudent to take notice but which does not have normative force.
Take a look at the ITU-T's "Author's Guide for drafting ITU-T Recommendations" for definitions of "corrigendum" and "implementors' guide." Also take a look at this passage in section 9.6.3 of the ITU-T's "Resolution 1, Rules of procedure of the ITU Telecommunication Standardization Sector (ITU-T): "...minor amendments may be covered by corrigenda rather than a complete reissue." No mention of IGs here; however, in section 9.6 of the same document, it says, "When a study group identifies the need for implementors >>>to be made aware of<<< defects ... in a Recommendation, one mechanism that may be employed is an Implementors' Guide. This Guide is an historical document >>>recording<<< all identified defects and their status of correction..." (emphasis mine). Therefore, an IG is informational; a Corrigendum is normative. If you think otherwise, please cite ITU-T text that backs up your assertion.

Paul:
I think you are incorrect on this. In SG16 implementors guides have always been treated as normative, and clearly are not implementors guides in the sense that you mention. They are formally approved by the entire SG, and become effective 'normative' after that approval.
