Hi Wendell,

I'm new to this myself, but in the spirit of participation...

Assuming the pipeline you want to call in looks a bit like this:

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" xmlns:c="http://www.w3.org/ns/xproc-step" xmlns:ex="http://www.example.com" name="pipeline01" version="1.0">

You can do the following:

<p:import href="pipeline01.xpl"/>
<ex:pipeline01 name="friendly-name"/>
<p:xslt name="subsequent-transforms>...</p:xslt>

Well, I only learnt about the p:load element this morning, but my first guess would be to get your base-uri for doc1 into a variable and do this:

<p:with-option name="href" select="replace($href, 'dir1', 'dir2')"/>

If you define the subordinate pipeline you should be able to reuse it easily enough for each document.

Perhaps the experts could confirm or deny this approach?
