Ok, only the structure of the document being layouted is XML.

If I insert a fragment somewhere in the document structure, the layout 
should adapt to the changes.

I feel now that this has nothing to do with Zope directly.

When we do stuff with ZPTs we are basically modifiyng XML structure.

Because todays user agents have not perfekt support for CSS based 
layouts and HTML is originally not an UI language we work around with 
extra markup and JavaScript.

This means that we want to be able to easily customize fragments of 
markup at any level (e.g. the <head> element), and associate it with 
spezial names - macros with their own namespace.

I think its up to the autor to say, this fragment is a pagelet or a 
portlet or a zopelet ;)

Er. I mean pagelet, sorry. The difference is explained here:

I like the document centric point of view. If we talk about layout we 
must reduce the scope of the discussion to a specific document type like 
HTML. (HTMLlet, hmm...)Oo. ?:-)
