+ // <set ... dur="1s" begin="<A-BEGIN>"/>
+ // <set ... dur="1s" begin="<B-BEGIN>"/>

+ // animA: attributes to be applied to a
+ // animB: attributes to be applied to b
+ // times: a series of triples which consist of:
+ // <sample time, a's expected start time, b's expected start time>
+ // * The sample time is the time passed to setCurrentTime and so is
+ // in seconds.
+ // * The expected start times are compared with the return value of
+ // getStartTime. To check for an unresolved start time where
+ // getStartTime would normally throw an exception use
+ // 'unresolved'.
+ // * We also allow the special notation to indicate a call to
+ // beginElement
+ // <'beginElementAt', id of animation element, offset>

+ // seek time.
