Internet Explorer has an attribute on anchor elements for URNs:
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.
