Looks ok to me :-)

Which "problem"?

Above you are not using the result of the first as an entry to the second.
The entry of the second is an XSP.
This is done by something like:
<map:match pattern="sendpdf">
<map:reader type="myzipsendoranythingelsereader"
src="cocoon:/generatepdf"/>
...

The generators have a source attribute to specify where to get the stuff to
process.
The chaining you are talking about is done by transformers usually...
But in you case you want stream-chaining/filtering, which Cocoon is not made
to do.
We could build it in, but there is not a big need; chaining requests between
sitemaps like above is the easiest way, since there is not more that a stage
usually.
Remember that it's a very costly processing to do.
