What do you mean by OK?
<param name='flags'>Pattern.COMMENT</param> could have been an option
but this isn't part of the current spec!
Note that you can have several pattern parameters in which case, it
wouldn't have been very clear to which pattern param a flags param
belonged...
In your regexp, you should take care that \d{4} allows any Unicode digit
not only [0-9]. That's why when you derive token datatypes, it's safer
to write [0-9] (if that's what you mean).
The other option is to use a xsd:date instead of token.
And if you want to leave days and months optionals, you can make a
choice between the corresponding WXS datatypes...
Hope this helps.
