Hi Olaf,

Actually I saw that we already discussed about this subject some time ago:
(06 September 2008 20:54) :-) Sorry for asking the same question twice. And
that you responded with more or less the same answer both time.

So there are 2 more test in the SVG Tiny 1.2 that do not test correctly the
"animation without from" case. What is worrying me a bit more, it that the
test animate-elem-227-t.svg actually explicitly test this case (an animation
without from attribute) and that the operator script describe the "wrong"
behavior as the correct one.

Regards

Julien

Once I had the same problem of a wrong assumption
for the timing of discrete to-animations in my test samples,
just because I did not find the related paragraph in the
old SMIL animation recommendation. But after a
question about this in the SYMM mailing list, it turned
out, that this is indeed already the defined behaviour
right from the beginning and applies therefore for
SVG 1.1 too.

'For the shorthand form to animation, there is only 1 value; a discrete to 
animation will simply set the "to" value for the simple duration.'
http://www.w3.org/TR/2001/REC-smil-animation-20010904/#AnimFuncCalcMode

I think, there are no incompatibilities in SMIL 2 or 3 and no specific rules
in SVG either, therefore such tests need to be fixed (as I already did for 
my own tests). And as far as I remember, it was already noted for
at least some tests in the official test suite as well ;o)
