| Propose a syntax?  All the ones I thought up were too ugly to live.  If
| you can come up with anything better I might implement it.

I think I'm willing to live without else. If I want else, I think the
right answer is a special-purpose XML vocabulary:

  <chapter>
    <prof:choose>
      <prof:when condition="html">
        <title>HTML Title</title>
      </prof:when>
      <prof:when condition="print">
        <title>Print Title</title>
      </prof:when>
      <prof:otherwise>
        <title>Print and HTML Title</title>
      </prof:otherwise>
    </prof:choose>
    ....

Where the profiling application always removes all prof: elements.

                                        Be seeing you,
                                          norm
