In general the aggregate has not been implemented in c3. However you can
do the same with a xml file for you define the includes and the
transform it with the include transformer. Regarding c) that is since
2.2 servlet: you can find some docs around it.

not sure what you mean but I think the include example in the c3 samples
will show you how to include.

well that depend on so many different things. If you refer "as is" yes
as construct. Actually all components work against urls. If you refer
whether the outcome is valid xml - you can make sure with the neko html
generator.

hmm they are normal urls. Query parameter are fully supported. Not sure
about the second part of the point but you can use {map:1} to access the
fist matching group of your match.

I am currently working on a project that is based on JSF. You can make
cocoon3 work along with anything it always depends on what benefit you
want to get from cocoon or another part. However as soon my project ends
I will look into using JSF in cocoon since I have to admit the form
handling and some contract/widget are really nice and easy to use.
However for form handling see the cocoon-wicket integration where you
integrate wicket into cocoon or vice versa depending on the main usage.
I you have many forms and little content you would go for the second option.
However there is no support for other controller then REST to access the
sitemap parameter.

Not sure.

Currently you have either a normal generator/reader/... but you can
implement a sitemap Starter and do as you please. However see the wicket
integration on how to handle other controller and cocoon side by side.

Please see the docs and the mailing archive it is really good covered.

As in URL calls, yeah why not.

Not sure about it, in 2.x there where a flag for it AFAIR and if so it
would be easy to migrate to c3.

It is no either or anymore since you can use c3 in a java based pipeline
for certain processes.
