Any published examples?  I know that the code's there in dbinfo.dsl, I was
hoping for something that actually extended things to produce output.

Ha ha.  That's easy for you to say.  You know what you're doing :-)

OK, to move this out of the abstract, suppose I have the following as
part of my document:

    <docinfo>
      <authorgroup>
	<author>
	  <firstname>Sean</firstname>
	  <surname>Kelly</surname>
	  <affiliation>
	    <address><email>kelly@ad1440.net</email></address>
	  </affiliation>
	  <contrib>Wrote the initial version of this chapter, 
	    provided the majority of the examples.</contrib>
	</author>
	
	<author>
	  <firstname>Jim</firstname>
	  <surname>Mock</surname>
	  <affiliation>
	    <address><email>jim@FreeBSD.org</email></address>
	  </affiliation>
	  <contrib>Edited and updated the chapter in preparation for
	    producing the commercially printed FreeBSD 
	    Handbook.</contrib>
	</author>
      </authorgroup>
      
      <date>Nth MMMM, YYYY</date>
    </docinfo>

By default, the stylesheets won't do anything with this information.  I can
get some of it to appear by putting

    (element docinfo (process-children))
    (element (docinfo authorgroup) (process-children))
    (element (docinfo date) (process-children))

in my stylesheet.  However, the affiliation information (and in particular,
the e-mail address) is ignored, as is the <contrib> stuff.

From what I can see, the stylesheets already have code to handle these
elements, in dbttlpg.dsl.  Can I (in my customisation) make it use the
existing formatting code for this information, or do I need to rewrite 
the code for this element context?
