failure to validate regex schema format containing '/' character

[orrisroot]

In FormatConstraint::validateRegex() method, '/' character has used for delimiter of preg_match() function.
If regex format contains '/' character, then schema validator always fails.
It seems to escape '/' character before preg_match() function call.

Confirmed - FormatConstraint::validateRegex() does not translate from ECMA-262 to PCRE, and does not escape PCRE delimiters. Thanks for reporting this.

I'm somewhat short on time at the moment - I've added this to my (long!) todo list, but you're welcome / encouraged to submit a PR for it if you want this fixed quickly :-).
