control solution for invoking of multimedia events by allowing
the timing information to be specified in terms of time, rather

invocation time for each multimedia event within one or more
extensible sequence sets of events is defined by a specification
in a HTML document which can be created by using a standard text
editor. Each of these extensible set of events corresponds to a
single multimedia timeline. This specification includes the
event, the time to invoke event and a sequence set. See page 8
