html - you - xml comment syntax multiple lines

HTML comments break down (2)

I have a page that is generated which inserts an HTML comment near the top of the page. Inside the comment is a *nix-style command.

<!-- command --option value --option2 value2 --option3 -->

This comment breaks the page completely. What is wrong with the comment to cause this to happen, and why is this the case?

Comments at the top of the page before <html> will throw IE into quirks mode, which could explain why the page breaks, if that's where your comment appears.

Comments in the XML Spec from the :

For compatibility, the string "--" (double-hyphen) MUST NOT occur within comments.
