Can someone please tell me if the page validator at validator.w3.org is correct indicating that the unescaped && in ja_bookmark is invalid code.
If this error is valid, could you please tell me how to fix it properly.
Thank you.

This message may appear in several cases:
* You tried to include the “<” character in your page: you should escape it as “<“
* You used an unescaped ampersand “&”: this may be valid in some contexts, but it is recommended to use “&”, which is always safe.
* Another possibility is that you forgot to close quotes in a previous tag.
