XHTML Validation

How well is the XHTML validation working?
I uploaded a file and the validator kept choking on this:
<!DOCTYPE html 
     PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

Does the .dtd file need to be present at this path on my system?  Do I have
to validate through my web server rather than file upload?
