What is the default namespace for HTML / HTML5?

According to this page, some user named "w3c" default namespace for HTML:

http://www.w3.org/1999/xhtml

He was clearly mistaken since xhtml was used for the failed XML4-based XML standard. What is the correct namespace should I use?

Background: I am writing an application using XML. I want to be able to store data in an XML node using namespaces. For example,

<s:Button width="100" height="100" html:color="blue" color="black" />

The XML parser requires a namespace for the "html" prefix.
