Comment (by peaceablewhale):

 Yes, when the page is served as text/html, DOM methods like
 document.getElementsByTagNameNS still works even though there is no
 xmlns="http://www.w3.org/1999/xhtml" declared because HTML does not
 support namespace and browsers put all elements in html in the HTML
 namespace automatically. However, when the page is served as
 application/xhtml+xml, the XML namespace is required as XML processing
 rules are now used and the default namespace is null.
