Brilliant.
Furthermore, I can return a nodeset with ids that share a common prefix (or
other substring):
<f:macro><![CDATA[=`//*[starts-with(@id,$idprefix)]`]]></f:macro>
If I had <ph> or <stentry> elements with ids all starting, say, "value",
then it becomes very easy to sum (or otherwise aggregate) these. It's a bit
of work to set up ids according to some useful scheme, but this could
obviously be done in a template.
You could even go further and use regular expression matching on ids (or
other attributes).

Yes.

Yes, and the same in DocBook 4 (@id) and 5 (@xml:id).

Yes, simply add:
---
<spreadsheetFunctions location="custom_spreadsheet_functions.xml" />
---
to your customize.xxe and add attached custom_spreadsheet_functions.xml
file in the directory containing customize.xxe and you are done.
custom_spreadsheet_functions.xml is:
---
<f:functions xmlns="http://www.w3.org/1999/xhtml";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:ns="http://www.w3.org/1999/xhtml";
xmlns:f="http://www.xmlmind.com/xmleditor/schema/spreadsheet/functions";>
<f:function>
<f:name>element</f:name>
<f:parameters>id</f:parameters>
<f:category>Custom</f:category>
<f:description>
<body>
<p>Returns a nodeset containing all the elements
(generally a single element)
having specified "id" attribute.</p>
</body>
</f:description>
<f:macro><![CDATA[=`//*...@id=$id]`]]></f:macro>
</f:function>
</f:functions>
