Internet Explorer has an attribute on anchor elements for URNs: http://msdn.microsoft.com/en-us/library/ms534710%28VS.85%29.aspx

Internet Explorer supports a non-standard attribute on the "A" element called "urn", which accepts an URN identifying some resource.

It is described in detail here:

It is not apparent that this attribute causes any behavior in the browser itself. It is possible that this is exposed to browser extensions in some way to allow them to overload the behavior of a link which identifies a particular class of resource.

It does not seem that this attribute has achieved wide author adoption nor wide application support.

IE's .urn attribute is present on *all* elements, and is part of IE's "namespaces". It's the equivalent of DOM's .namespaceURI.
