Do you mean they should be outside the document-root altogether?

The viewport entity just needs a "location" attribute that points to
"../" by default. Viewports are then just the same as any
xref/block reference element except with a boundary.
This way, paperspaces are normal directory/drawings that can live
anywhere. They can even exist deep inside categorisation
sub-directories of the parent drawing.
Paperspaces can be distinguished from other drawings/blocks/symbols
by a "print" type of element in the parent drawing that contains a
path, a zoom scale and paper size.
