Scripting	t:PRIORITYCLASS.higher [ = sHigherPriority ]

DHTML可能的值

sHigherPriority String that specifies or receives one of the following values.
pause Default. If a higher priority element begins while a child element of this priorityClass is active, the active child element is paused and resumes when the interrupting element completes its active duration. The paused element is added to the top of the pause queue.
stop If a higher priority element begins while a child element of this priorityClass is active, the active child element is stopped. Any paused elements are also stopped, and the pause queue is cleared.
The property is read/write. The property has a default value of pause.
