Thanks Cathi,

I had it on my todo list to look for those articles. If I remember correctly (and I probably don't, from a year ago,) you also need a line referencing the XSD in each aspx, ascx file--?

If I'm thinking correctly (and I'm probably not, long day,) couldn't the building of that XSD be automated by investigating the relevant classes by reflection? This would be over my head at the moment, but I'll look for something that might exist...
