Instead of criticizing what ShEx can't do we should all try to see what
ShEx should do.
I think we all agree that a compact human syntax (with equivalent RDF
representation) that covers common validations cases and SPARQL extensions
is something we all want.
I too don't like some parts of ShEx but I think it's a good initiative to
bootstrap a standard.
I already raised some issues in the mailing list and have a few more from
my experience with RDFUnit - but will raise them later since the
maintainers are now too busy replying.

Best,
Dimitris
