Give or take a few quibbles, 303 and rdfs:seeAlso are
pretty much equivalent.  If such "conformance" is really
required then wouldn't there also be a need for a
strong version of rdfs:seeAlso with similar guarantees?
If such a property hasn't been missed for a while then
surely that's an indication that this conformance
rule is not required.
