I have encountered a problem using the W3C HTML Validator service.

In attempting to upload and parse some XHTML documents, I noticed that
uploading files whose extensions are ".xhtml" do not parse correctly. 
I tried a couple of files called ".xhtml" and received the following
error message:

Fatal error! cannot open "DTD/xhtml1-strict.dtd" (No such file or

I couldn't parse this document, because it makes reference to a
system-specific file instead of simply using a public identifier to
specify the level of HTML being used. 

You should make the first line of your HTML document a DOCTYPE
declaration ... (examples)

However, renaming these files to *.html produces the intended results.

Please find attached a simple example, called "_emptyframe.html", which
parses successfully as XHTML 1.0.  (Validation failed completely when
the file was called "_emptyframe.xhtml".)

Any idea why this is?  Should XHTML files still be named *.html, or is
this a problem with the validator?
