I'm not sure what the clause means either, but my best guess is a weak
version of 1(a) together with 2(b) (referring to Andrew's descriptions
above, not license sections). By weak, I mean that it doesn't require
a machine-readable version of changes. It would be great if the
language were more explicit, or if it already is, a German speaker
But I'm not sure any of above readings would make the proposed
attribution license non-Open. 2(a) is problematic, but then all
previously-deemed-Open CC BY and BY-SA licenses have that. As they do
require a weak version of 1(a). And previously-deemed-Open licenses
includes a strong version of 1(a), in particular ODbL does, as an
alternative to full source distribution (which may or may not be less
onerous depending on circumstances; OTOH maybe as an alternative it is
OK, but without full source option it is not).
Though I'm not certain above readings would make proposed license
non-Open, I'd recommend both making conditions more clear and ensuring
they are minimal -- this presumably aims to be a permissive
attribution-only license; its effectiveness as such will be greatly
limited by difficult to understand and possibly understood as onerous
