Remarks

There is only one instance of this attributes collection. It is available only from the ContextAttributes collection. If the ContextAttributes collection is for a window, then HighPriorityAttributes returns nothing.

These attributes are always in effect, and they are the highest in the context bag precedence, resulting in matching topics going to the top of their respective categories.
