First of all - huge thanks for MPS product.
I have a couple of questions and first - what is a difference between "Used" and "Extended" languages property of a model?
- Used language - if module A uses language L, then models inside A can use language L.
- Extended language - if language L extends language M, then every concept from M can be used inside L as a target of a role or extended concept. Also, all the aspects from language M are available for use and extension from the corresponding aspects in language L.
This is not completely clear for me. What other "uses" a language can have, except mentioned in second item? Could you please give some examples
