Thanks for digging that up. I think the author of that may actually have been a bit confused... or at least, they didn't state the facts clearly. (There may have been a bit of propagandizing there, as well, to get people to use XML namespaces more, perhaps.) Indeed, if you try to set a namespaced attribute with setAttribute(), it won't work correctly... the attribute will be placed in the null namespace. So, when you use el.setAttribute( "xlink:href", "#foo" ); it's the equivalent of using el.setAttributeNS( null, "xlink:href", "#foo" ); where the local node-name (unintuitively) is 'xlink:href', not 'href' in the XLink namespace. But that's only when you're dealing with namespaces. Since most attributes are in the null namespace, and setAttribute() places everything in the null namespace, then these are equivalent and perfectly safe: el.setAttribute( "fill", "#f00" ); el.setAttributeNS( null, "fill", "#f00" ); As an aside, this is actually a rather poor design, which could have been made better if they had simply accounted for hardcoded prefixed to be bound to specific namespaces, rather than introducing the arbitrary level of abstraction where any namespace could have any prefix string; this is made a bit simpler in HTML5, which does define a few hardcoded prefixes for namespaces. Maybe in some future version of XML, XML Namespaces, or the like, this can be be expanded beyond HTML.
