    Instead of <!DOCTYPE html>, using this <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    It's the doc type. Eclipse is going to validate the DOM against the DTD. If unknown entities are not clearly defined in the DTD, then Eclipse will raise warnings.

    In the absence of an explicit doctype, you should check if the Property dialog for the file has a page for deciding what doctype to use as a default. HTML5 was only very recently added: http://dev.eclipse.org/mhonarc/lists/wtp-dev/msg07790.html .
