Yes, that's an excellent reference. Note that it echoes
the original design principles of the web:

-------------
http://www.w3.org/pub/WWW/DesignIssues/DosDonts.html
timbl, circa 1990

Short UDIs

UDIs should be kept short and devoid of information that
indicates the mechanism by which the document is
retrieved. (in the theoretically clean implementation, the
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
protocol information should not be present).
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The motivation is that when a document changes
implementation (e.g. from being a file to being part of a data
base, or by moving to a different location, the anchors
pointing to it should not have to change.
