Is worth nothing that is not HTML but a common developer practice is to comment out parts of metadata so that it will not be rendered and/or executed in the browser. In HTML, commenting out multiple lines can be time-consuming. It is useful to exclude pieces of template structural metadata containing comments, CSS or code and systematically commenting out to find the source of an error. It is considered a bad practice to comment blocks out and it is recommended to use a version control system. The attribute "type" is required in HTML4 and optional in HTML5.
