Its not clear if you are using ASP.NET 1.x or 2.0. ASP.NET 1.x is not compatible with W3C validators, especially when it comes to XHTML. ASP.NET 2.0 is compatible with XHTML, although there remain a few small bugs. (In particular, I've found that the Image
control's Align property is incorrectly generated.)
If you are seeking validation compatibility, use ASP.NET 2.0. If you happen to find a bug while using ASP.NET 2.0, report it to Microsoft so it can be addressed in a service pack.
