Related notes:

no change required; the use of clock-time expressions is permitted by SMIL with the @dur attribute, and such usage appears to be well defined, in the sense that when used with dur, the clock-time takes on the meaning of a difference between two clock times;

reopening this issue: rather than just closing without any change, should add informative note to @dur explaining intended interpretation of clock-time;
