<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>A new RFC (<a href="http://trac.osgeo.org/fdo/wiki/FDORfc11">http://trac.osgeo.org/fdo/wiki/FDORfc11</a>)
has been posted. The RFC follows up on RFC 8 by adding geometric functions to
the list of well-known FDO functions. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Please review the RFC. Any comments/suggestions and
questions are welcome. All feedback is expected by the end-of-day <u>September
12<sup>th</sup> 2007</u>. If no changes are required it is my intent to motion
that a vote for the acceptance of the RFC be made and subsequently voted on by
the PSC.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
