In that case it is possible to plug in other relation store backends
(e.g RDF) that do not support genuine triadic predicates, which means
that only "local folder" types of slots will be available, but some
relation storage is required for the dyadic relations between elements
and styles, widgets... because the relations between the elements are
not stored on the elements themselves.

yes, I re-read
http://mail.zope.org/pipermail/zope3-dev/2004-December/012852.html and
while going through the different definitions I saw that not two
implementations are done in the same way, which is fine.

The important aspect is that "portlets" or  "pagelets" as they are
implemented in cpsskins separate model and view.
They implement the "data model" part only,  not the view itself, which
is done later by widget, layout and style filters inside the rendering
engine.

Of course it is possible for a "pagelet" to render HTML directly and
consider the HTML produced as data (that's a question of semantic), but
then other rendering engines (text-based, SVG, RSS, ATOM, etc.) won't be
able to do anything with the HTML data that they get.

Anyway, pagelets or portlets whatever they called and no matter what
data they produce (structured data or raw HTML) must be "pipe-able"
through the rendering engine, i.e. they must return some data, the more
"ready HTML" the data is the less reusable it will be.
