Ok, yet another reply gone wrong. ;-)

Hi Oliver,

we never did. And that's why they are _not_ part of the interface (i.e.
dune/grid/common/capabilities.hh). Yet, Geogrid tries to take advantage of
them and therefore needs this capability to work on that grid. So, if you want
GeometryGrid< YaspGrid >, you need this capability, otherwise not.

Of course, we can decide not to add this capability and leave it up the user
to declare it. I would leave that decision up to the grid implementor...

I hope this course of action was not an offense against good style - I just
needed this capability to make it work.

Yours,

Martin
