Error: there is no attribute TITLE for this element (in this HTML version)
There is no attribute 'title' because there is no element COMMENT. It's a malformed HTML comment. It's written as if it was an element. See here how to write a comment.

Is it possible that NVU changes the html text, causing errors when it is displayed on the Internet Explorer browser?
