I want to use the CIncludeTransformer to call another pipeline and pass it XML using the POST mechanism. Before posting this question, I tried to make my way through the Source code, eventually finding my way to the SitemapSource class. It doesn't look like the cocoon: protocol allows for POST. Is this the case?
The cocoon: protocol doesn't support POST.
The cocoon: protocol does not support GET either. As a matter of fact, it is not an HTTP protocol at all. What it does support though, is cocoon: protocol URI which allows for request parameters.
You can always stick your XML into request attribute. I'm puzzled though, why would anyone need to do something like this ...
It is not very likely that it will either. I added POST support to the HTTP: protocol in Bugzilla (http://issues.apache.org/bugzilla/show_bug.cgi?id=24402) for web serivce support. But some people at the list thought that it was going outside the intended scope of resources to make them postable.
You sure did went outside of the scope :-) It's good functionality to have in something like HTTPRequestTransformer, but not in SourceWritingTransformer or CIncludeTransformer (the new transformer, IncludeTransformer, does not have such complications).
I guess a side question is, is there a better way to pass XML to another cocoon pipeline as input to it. It is pretty easy to call another pipeline and get its output, but I want to pass XML to another cocoon pipeline.
I'd be fine with a solution that uses flowscript.
I think the easiest way is using flowscript. You can use the ModuleSource, "module:request:inputStream" (http://wiki.apache.org/cocoon/ModuleSource) to get the input stream.
Then you can use org.apache.cocoon.components.flow.util.PipelineUtil.processToDOM to get the content to a DOM that you after that can put into the pipeline with e.g. JXTemplateGenerator.
Hm. I'd probably go with using request attribute and then generating XML directly from there in the included pipeline - no JX and no Flow. It depends on usecase, of course.

P.S.
I am not on the dev list, so if you could copy me in on the answer, that would be great!
It is considered slightly impolite to ask for private copies as it hints that you only want something from us and not are going to contribute. And that can reduce the chance for geting answers. See e.g. http://jakarta.apache.org/site/mail.html and http://www.catb.org/~esr/faqs/smart-questions.html.
You can always read answers through archives: http://marc.theaimsgroup.com/?l=xml-cocoon-dev&r=1&w=2 e.g.
