It looks like you are using ASP.net, which is unfortunately known to  
serve proper XHTML to browsers and pathologically broken markup to  
other user agents, including the markup validator.

This is _not_ a bug in the W3C Tools.

For more information on this “feature” in ASP.net, and how to work  
around it, see this document:
and in particular the section "Configuring Browser Capabilities for  
Markup Validation".
