Definitely not - RFC1738 says:

   As a special case, <host> can be the string "localhost" or the empty
   string; this is interpreted as `the machine from which the URL is
   being interpreted'.

It does not authorize omitting the // too as in file:/dev/null.  On
the other hand, the example you quote from the test suite uses it as
the system id for a notation, which is not required to be dereferenced
by the XML parser and whose use is implementation defined.  The same
goes for the use of "scheme:" and "d:", which appear in the system IDs
of unparsed entities.
