OK. So, just to make sure that I get this right: for locales A and B where A contains the theorem a

  context B begin
    context begin
      interpretation x: A
    end
    theorems b = x.a
  end

would enrich B by b but not x.a, right?

Quoting Florian Haftmann <[email protected]>:

context B begin
  context
  begin
    interpretation A
  end
end

This looks attractive, but could you please elaborate the semantics:
- What would be the effect of the interpretation from the inner block on
the outer block?

The interpretation would only affect the inner block.

- What would be the effect of the entire sequence on B?

None.

In other words, you can think of

context B
begin

...

interpretation A

...

end

being equivalent to

context B
begin

...

context
begin

interpretation A

...

end

Cheers,
        Florian
