In terms of using names to associate content with slots, we already have
named flow idents from css3-regions to use. So your slot-content-assignment
syntax could change to something like this (I'm adding an element property
to associate the article element(s) with one or more paginated templates)

 @page fishy {
   @slot {
     /* positioning */
     flow-from: sushi;
   }
   @slot {
     /* positioning */
     /* no content or flow-from declaration, so use normal flow */
   }
 }
 aside { flow-into: sushi; }
 article { master-template: fishy; }

If a slot has no content assigned to it with the 'content' or 'flow-from'
properties, then it defaults to normal flow. You can create a paginated
template that does not accept normal flow by making sure that each slot has
assigned content.

Thanks,

Alan
