I think that would be a more robust output format, technically, easier to
adapt, and more readily conform to the strict XHTML tag subset.

The other issue I encountered was this:

\startfrontmatter
  \startstandardmakeup
    Title page
  \stopstandardmakeup

  \startstandardmakeup
    Copyright
  \stopstandardmakeup

  \completecontent
\stopfrontmatter


This produced "*Title pageCopyright*" as text without any markup, which
makes the EPUB output a bit difficult to parse. I thought the software
should output something like:

<div class="frontmatter">
  <div id="standardmakeup1" class="standardmakeup">Title page</div>
  <div id="standardmakeup2" class="standardmakeup">Copyright</div>
  <div class="contents"><!-- etc... --></div>
</div>


This way the title and copyright pages can be styled independently.

Kindest regards.
