Hello,
The doctype in my (X)HTML documents is written in lowercase (but not the 
formal public identifier) :
<!doctype html public "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

That’s a problem with the validator, it can’t validate my documents.

At 
<http://lists.w3.org/Archives/Public/www-validator/2002Nov/0099.html>, 
that’s written that we get that error because of the SGML rules.
But at 
<http://www.htmlhelp.com/tools/validator/problems.html.en#doctype-case>, 
that’s written that the quoted string that appears after the PUBLIC 
keyword--is case sensitive (not before).

Now the question is : Must I write the doctype in uppercase or not?
<!doctype html public "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
or
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

If you want to see my website with a doctype in lowercase :

I hope someone can help me, thanks and sorry for my English skill, I’m 
French.
