Hi Mark,

If you review the commit here:
http://postgis.refractions.net/pipermail/postgis-commits/2007-November/000191.html you can see the changes. The part I found confusing was how for some of the curve types with sub-geometries, the parse_wkb() function was called recursively. Now from the examples in the HTML documentation, I could see that not all of the constituent parts of the new curve types had the constraints you mentioned above - hence the check is a little bit "loose" at the moment.

If you can confirm that the WKT and WKB parsers are working as expected
for the curve types that would be appreciated; however the new release
is pretty much ready to go...


ATB,

Mark.
