Dear Esseger, 1. Interpretations can be given name prefixes to avoid clashes. For example, interpretation prefix!: AAA M2 T2

That's exactly what I need, thanks a lot.

2. Unfortunately, the sublocale command does not export the rule for showing the locale predicate of superlocales. Consequently, I recommend to first prove sublocale proof obligation in a lemma and then use the lemma for discharging the goal in the sublocale command. Here's an example: context AAA begin lemma BBB: "BBB M T" <proof> sublocale BBB M T by(rule BBB) end

Best, Esseger
