It isn't a "seeming" difficulty, it is a real problem. Two syntaxes
are much, much less useful than one. Having two or more ways to say 
the same thing (zip, jar, and cab for Java) is almost always a bad
idea. The reason given for the compressed RDF syntax, "it's smaller",
is never a good enough reason. Either use the small one, use the clear 
one, or make one that is small enough and clear enough. Specs are
the wrong place to prevaricate.
