To simplify further I changed the "comment" down to only 2 dashes: problem still exists for both firefox and the validator. this is the output:
<!-- -- --> This is the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml"> <head> <meta http-equiv="Content-type" content="text/html;charset=UTF-8" /> <title>mytitle</title> </head> <body> <!-- -- --> </body> </html> The problem disappears for both firefox and validator if the "comment" is further shrunk to only 1 dash. The web page is then blank.
