Spoke too soon.

You need to specify the output for the p:for-each for the pipeline but
specify what replaces the element for the inner steps.

Attached is a tweak to the schema and pipeline.

<p:pipeline xmlns:p='http://www.w3.org/2006/XProc'
         xmlns:c='http://www.w3.org/2006/XProc/Components'
         xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
         xsi:schemaLocation='http://www.w3.org/2006/XProc pipeline.xsd'
         xmlns:xhtml='http://www.w3.org/1999/xhtml'
 
xmlns:t="http://www.smallx.com/Vocabulary/Services/Tideinfo/2005/1/0"
         xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <p:input name="large-doc"/>
    <p:output name="result" from="final"/>

    <p:for-each select="section" over="large-doc" to="iteration" 
replacement="transformed">
       <!-- input isn't needed here because this "for-each" has
            to iterate over elements.  The input is identified by
            the 'over' attribute and the binding for each result
            element is specified by the 'to' attribute. -->
       <p:output name="final"/>
       <p:step kind="p:xmlbase">
          <p:input name="input" from="iteration"/>
          <p:output name="based"/>
       </p:step>
       <p:step kind="p:xinclude">

          <p:output name="transformed"/>
       </p:step>
    </p:for-each>

</p:pipeline>
