Still a newby, but definitely understanding a bit more about the
concepts of cocoon 2, i think are your
probably confusing different levels of requirements with regard to
change --- or just like me a couple of
days ago, not getting to grips completly with the concepts of cocoon 2,
what is dynamic and what should'nt be....

The sitemap is "fairly" static by definition, but dynamic by usage .....
With "fairly" i mean: you can change the sitemap,
it can grow, it can get smaller etc, but not in the same with the same
life-cycle as the content and even structural
apperance of your site. The sitemap defines all potential pipelines,
aggregations, filters etc.of all possible structural
combinations to produce dynamically the content of your site. This
surely does not have the same change cycle as content
and structural appearance itself, and it can be complex: just like the
structure of a structure
of a specific sentence of a language versus the structure of the
language itself. You can "produce" language in a
fairly dynamic and creative way, but the underlying structure, albeit
fairly complex, is at any given time static.
It evolves also, but very slowly ...... Ok, the comparision does'nt
suite all that well, since we are "inventing languages"
all the time .... the life - cycle of a site is much shorter than with
our "natural" language, there may requirements
for managing different overlapping life - cycles of different sitemaps,
just like with any code, but that does'nt mean that the
sitemap is dynamic. This goes more into the realm of configuration and
change management of "code" .... see also the link:
http://chello.sourceforge.net/
For early stages of developing complex sites, i also would'nt use
cocoon2 that much, but tools with which you can fairly
quickly prototype your requirements. After you know more about your
requirements, move on to cocoon2, it will help you
greatly! If at poiint you have requirements to be able to apply
different structural combinations dynamically
depending on eg. user preferences etc. That is done generatively by
using generators by combining different
pipelets (cinclude/xinclude) dynamically , by filtering and/or by
aggregation based on the "same" it is "static" sitemap.

Specially if unnecessary ......
