It states as well, that from-to, from-by and by-animations have to be
equivalent to specific related values-animations, therefore of course
keyTimes apply for them as well, else it would be not equivalent.

Because to-animations are not equivalent to values-animations and
have a specific definition of the animation effect, several attributes do
not have a visible effect for to-animations, keyTimes is one of them,
because the timing is already completely defined.

Are there already ideas how to indicate an SVG 1.1 second edition
document, for example version="1.1.2" or something like this?
This becomes more and more important, if the number of incompatible
changes of definitions in the second edition increases even more ...
Else having two definitions for one feature effectively results in an
undefined feature again, that authors should never use (and
implementors not implement) ...
It is a difference to fix bugs in the second edition or to define
things, that are undefined in the first edition or to fix contradictions
in the first edition compared to a situation with a change of a 
defined behaviour.
