} Format the PageSequence. The PageSequence
formats Pages and adds them to the AreaTree,
which subsequently calls the StreamRenderer
instance (this) again to render the page.
At this time the page might be printed
or it might be queued. A page might not
be renderable immediately if the IDReferences
are not all valid. In this case we defer
the rendering until they are all valid. |
