The thing is I generate a stylesheet in B which is used in A (and in other
pipelines):

<match pattern="B">
  <map:generate src="resources/{filename}.xml"/>
  <map:transform src="styles/Meta_output.xsl"/>
  <map:serialize type="xml"/>
</map:match>

Note that the output of B is a stylesheet (say output.xsl).

Then the first thing that comes to mind is using the Cocoon protocol to read
this output.xsl as the src of the transformer in A:

<match pattern="A">
  <map:generate src="resources/bla.xml"/>
  <map:transform src="cocoon:/B"/>
  <map:serialize type="html"/>
</map:match>
      
But unfortunately this does not work. (I have posted messages on this matter a
few days ago). The output of A is not what it should be at all. 

So I thought a workaround is to write the output.xsl to file and then read it in
A. But then I had the issue of dependencies....

I hope i have been clear enough. By the way have you ever tried to use cocoon:/
as the src of a Transformer?

Thanks,
Ali
