But this sounds to me, like the problem is, that your external library
is based on different referenceelements than dune. As what I
understand, your lib would also fail, if all normals were oriented
outwards. Right?!

If this is the case, then it is obviously an issue of your program,
because dune can not have the fitting reference lements for each and
every lib out there.
