I think, there is not much choice, because the behaviour depends on 
SMIL and the definition, which values for the animated attribute
or property are ok. If an empty value has a defined meaning for the 
animated attribute or property, this is a well defined behaviour for
animation. Else it would be not possible to use such an empty value
for animation at all, even if this is defined for the attribute/property
without animation. The viewer cannot ignore a trailing ';' even if
an empty value is wrong, because the complete timing depends
on the number of ';' in the values attribute.
See the example I already gave for the animation of xlink:href
in SVGT1.2 - maybe there are a few other attributes or properties
with a defined meaning of an empty value.
As defined in SMIL, the viewer has to analyse with respect to the
attributeType, whether the used values are correct or not, then 
such an empty value is no specific case, it is yet another value
to analyse if it is applicable for the given attributeType or not ;o)
