hi all, a question about libhubbub and namespace

Hi all.

I was reading the example libxml.c provided in the src of libhubbub.
And found that it assumed that all html page had namespaces below:

/**
 * Mapping of namespace prefixes to URIs, indexed by hubbub_ns.
 */
static struct {
    const char *prefix;
    const char *url;
} namespaces[] = {
    { NULL, NULL },
    { NULL, "http://www.w3.org/1999/xhtml"; },
    { "math", "http://www.w3.org/1998/Math/MathML"; },
    { "svg", "http://www.w3.org/2000/svg"; },
    { "xlink", "http://www.w3.org/1999/xlink"; },
    /** \todo Oh dear. LibXML2 refuses to create any namespace with a
     * prefix of "xml". That sucks, royally. */
    { "xml", "http://www.w3.org/XML/1998/namespace"; },
    { "xmlns", "http://www.w3.org/2000/xmlns/"; }
};

However, take aol.com as example. It has namespaces below:

<!DOCTYPE html>
<html  
xmlns:og="http://opengraphprotocol.org/schema/"xmlns:fb="http://www.facebook.com/2008/fbml"xmlns="http://www.w3.org/1999/xhtml"xml:lang="en"lang="en"class="Gecko
 ff2"id="global-header-light">
... ...
So, the Question is: how to automatically create namespaces for html pages such as aol.com ? 

Thanks a lot.
