RFC4408 section 6.2 explains what happens in case of an empty
domain-spec ( "exp" "=" domain-spec ).

Madness, <domain-spec> is never empty.  That's an erratum, the
prose you've quoted and the syntax have to be updated, something
like this:

~~~ old ~~~
   explanation      = "exp" "=" domain-spec
~~~ new ~~~
   explanation      = "exp" "=" [ domain-spec ]
~~~ end ~~~

Ugly like hell.  Maybe it's better to fix the prose so that it
matches the existing syntax (?)
