Lets suppose we have a document in the top level object named global_map
with an entry like:

<A HREF="<!--# var title-->"><!--# var title--></A>
<A HREF="<!--# var BASE1--><!--# var title-->"><!--# var title--></A>
 
How should the relative URL's or BASE variables be handled if this
document is called from a subobject down the
object hierarchy like <!--# var global_map context=origin--> ?

Anyway if you do need to access the parent of a given object you can use:
<!--# var "aq_parent.<whatever method you want to call>"-->

but I think one must be careful then of relative URLS.
