<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Verdana","sans-serif";color:#1F497D">The Trac page sketches the design, but I bet you have come across some subtleties as you implemented it. (Exports for one.) Would you be willing to expand
the design specification (as seen by the programmer) to be as complete as possible? Include some examples. This would best be done on the Trac wiki rather than in the ticket itself. Most of text can come from the existing writeup, but I expect you have
more to add. (Or maybe not... maybe it all turned out to be very simple.)<o:p></o:p></span></p>

<p>Hi,<o:p></o:p></p>
<p>I've updated the Trac ticket with the latest status of my work. There are only two loose ends remaining, and my hope is that the second one will turn out to be some trivial oversight on my part.
