- I think the test has a problem with the meaning of some units.
The relation between px and absolute units like cm 
depend on the resolution of the screen - therefore the
gray marker lines should be provided with the same units
as the used animation values (or see below with a user
dependent calculation of values or positions).

- The description is somehow surprising as well -
"Test possible values for 'calcMode="spline"', with both commas, whitespace, 
and mixed separators"?

- missing unit ex?

- Note, that SVG tiny 1.2 and SVG 1.1 depend on CSS2.0 and
luckily not on the new CSS2.1 draft with obfuscated absolute units
(I sent already an LC-comment to www-style@w3.org
about this problem in CSS2.1), therefore such tests are
tricky. I have some in my test suite and the results with current
viewers are disappointing, not only due to their problems with
absolute units, therefore in general it is of course a good idea
to have such tests, but I think, for mixes of px and absolute
units it has to be interactive (PHP script for example) to allow
the tester to provide information about the current resolution
(relation between px and mm).
