Do not confuse XHTML and HTML.
XHTML is HTML ruled to be a valid XML document. Actually the XHTML 1.1 standard does not apply to HTML 5 but to HTML 4.01.
What does it mean? You can pick a valid XHTML 1.1 document and it’ll be a valid HTML 5 document but the counter-part is not always true. For example:
It’s valid HTML code (it doesn’t matter which version) but it’s not a valid XML statement (then it’s not a valid XHTML document) because of the empty attribute. World is full of these examples (just Google), HTML is very relaxed about syntax (and HTML 5 didn’t change this direction) and there are some other differences too (here, for an example). Moreover the HTML 5 standard introduced new tags that aren’t part of XHTML 1.1 standard so a fully featured HTML 5 document (despite the syntax) won’t be a valid XHTML 1.1 document.
