Ah, so you want layout template authors to be able to define slots with 
semi-meaningful names, then programmatically fill those slots with 
either a content-selector widget or the selected content.  The fact that 
'fill-slot' only accepts a literal string isn't a surface detail -- 
you'd have to go deep into the guts of the TAL interpreter to change 
that. The best way I can think of to deal with this is to actually 
generate the ZPT text with the slot names filled in, as in the example 
above, and compile the text as a template.
