- * 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.
