I think, the deeper sense of tests is to find out, which viewers deviate
somehow from the recommendations, not that every viewer with
an arbitrary interpretation passes all tests ;o)

And note, that the 't' in the name of the file and the doctype indicate, 
that it is a test using the tiny profile. 
And for this profile the value of 'font-size' has never units. 
The test would get wrong by adding units.
Additionally for tiny 1.1 attributeType="CSS" is practically meaningless,
because there are no properties available for this profile, 
authors can only use presentation attributes - and those are without
units in this profile. 
Units are only allowed for the attributes width and height of the (root) svg 
in tiny.

And even for a document using the full profile, one can use units,
but there is no need to do it in this example - to add 'px' or 
attributeType only  increases the file size with no effect.
But this might be another interesting test, in which viewers the
animation with units works in a full profile document.
Similar interesting is the question, whether the interpretation of
attributeType is really correct in cases, it has an effect (due to
my tests there are bugs in several viewers).
But these are additional tests for the full profile, not related
to this document.
Of 'academic' interest could be a test result for attributeType="CSS"
in a document using tiny 1.1. 
Hopefully no author will do it, my test about this indicates (different)
problems in several viewers as well ;o)
