Worked through the editorial corrections to the Sawhill article, and made all the fixes. Also had to make two code changes: in the first, the need to add an acknowedgement that a previous version of the article had been a prize finalist was handled by placing a paragraph with a special rend attribute in the <sourceDesc> tag:

<sourceDesc>
  <p rend="afterTitle">A version of this paper was selected as a Henderson Plenary Award Finalist at the IALLT 2007 Annual Conference.</p>
[...]
</sourceDesc>

Code in xhtml_article_base.xsl looks for this and renders it above the author names. This is only marginally satisfactory, but again, there are no absolutely appropriate tags for this kind of thing because it's peculiar to born-digital documents.

The other change related to capitalization of initials in bibliographical references. My code was automatically doing this, but the case of "bell hooks" (an affected pseudonym; the author always uses lower-case) required that automatic upper-casing be suppressed. Conceivably there are actually first names that might legitimately begin with lower-case letters anyway, so it's no bad thing as far as I can see.
