[isabelle-dev] Interpretation in arbitrary targets.

What you currently have in many places (e.g.
http://isabelle.in.tum.de/reports/Isabelle/file/757fa47af981/src/HOL/Lattices.thy)
is the pattern.

  context B begin
  …
  end

  sublocale B < …

  context B begin
  …
  end

  sublocale B < …

  context B begin
  …
  end

When giving up the paradigm that sublocale dependencies may only be
introduced on the global level, youo end up with sth like

  context B begin
  …
  intepretation …
  …
  intepretation …
  …
  end

which is compacter and more intuitive.
