Possible DOM bug in Firefox
I found what appears to be a bug in Firefox 1.0.4. Using JavaScript, i'll append a new DOM node, a link, into a web page. Using Link.setAttribute( 'href', 'http://www.mit.edu/' ) the link is clickable, but using Link.setAttributeNS( 'http://www.w3.org/1999/xhtml', 'href', 'http://www.mit.edu' ) it is not.
