No, I don't see it that way. The question isn't whether it's OK to use local layout of higher versions. The question is whether we should *routinely* update the format for a new release. If there was some reason to do so---for example, you want to make use of some feature only available with later formats---then that'd be differfent. Note also that the use of higher formats does NOT mean the document cannot be exported. It means one will have to do manual fixup of local layout, to reduce the format number to something appropriate. But people who are messing with local layout will be able to handle this. It's a super-user feature. Still, we probably should issue an appropriate warning when we do the conversion. Richard
