This looks like there is something in the XSL copying the contents of 
all elements into your output document, but not processing it.

it seems that my stylesheet is not used at all... :(

First we need to verify that you request is actually being processed by 
your plugin. A quick and easy way to do this is to force an error:

forrest run

then in another console:

edit the sitemap so that the line:

<map:transform src="resources/stylesheets/document2mxml.xsl"/>


<map:transform src="resources/stylesheets/document2mxml.xsl-error"/>

(note the addition of "-error" to the src)

"ant local-deploy"

Now request the page, if it is being processed by your plugin you should 
see an error saying that the XSL cannot be found (as expected). If you 
recieve this error then you know that Forrest is trying to process the 
file using your plugin XSL.

I suspect that you will find it is being processed, the above is only to 
verify this is the case since you say you think it may not be being used.

Assuming that it is being used you can then comment out the 
transofrmation line, do "ant local-deploy" and request the page again. 
You should now recieve the document in its raw format.

Assuming that this all goes to plan we now know you have a problem in 
your XSL file.
