Re: <optional> vs. <zeroOrOne>

[Kohsuke KAWAGUCHI <kohsuke.kawaguchi@eng.sun.com>]

Although I can live with both, I prefer <optional> more because...

1. TREX uses <optional>, so it's natural to use the same keyword, and I
   don't see any strong reason to change it.

2. One can argue that optional and zeroOrMore/oneOrMore are different
   things because the latter represents a repetition while the former
   doesn't. So keeping three names similar is a bit of over-generalization.
