[postgis] GML generation scripts and question: attachments

[Hisaji ONO]

 Hello, Mr. Rogers.

 Thank you for your nice php script.

 I've uploaded WKT-to-SVG php script. Howeber compared to you script, my
script was too complicated and ugly. Too many usages of PostGIS functions.
So I'd like to improve my script to refer your script.

 Regards.
