i spent a long time last night looking for some php code that would validate your xml based on an xml-schema.  no luck.  there seems to be support for something called schematron, but i didn’t look into that.  it’s probably going to take a while to get to that level of design.

in the meantime, i’m going back to the XMLeditor to finish off the last few stages.  i would really like to get it working by the end of the weekend.  Then i can get it out there and mike and alan can comment on it.
