* Modified by Mark Lillywhite, mark-fop@inomial.com. No longer keeps
a list of pages in the tree, instead these are passed to the
StreamRenderer. No longer keeps it's own list of IDReferences;
these are handled by StreamRenderer. In many ways StreamRenderer
has taken over from AreaTree and possibly this might be a better
place to deal with things in the future..?<P>
Any extensions added to the AreaTree while generating a page
are given to the Page for the renderer to deal with.
