No.

  empty, element foo { empty }

is equivalent to

  element foo { empty }

whereas

  token '', element foo { empty }

is illegal.  However,

  element foo { empty }

will (I think) match the same things as

  element foo { token '' }

Can you give an example of an annotation that is functionally a pattern and
how such an annotation would be used?

Where do you propose allowing this?  If it's allowed anywhere that a pattern
is allowed, then the problem is that

  extension QName { ... }*

would be legal, but

  <zeroOrMore><QName>...</QName></zeroOrMore>

isn't.
