[Bug 1922] 'x' regex flag not entirely clear

------- Additional Comments From ashok.malhotra@oracle.com  2005-09-13 21:32 -------
On the joint 9/13 telcon the WGs agreed to change the explanation of the 'x'
flag based on the Perl semnatics as suggested by Liam.  Suggested replacement
text is below.  Please comment.

x: If present, whitespace characters in the regex are removed prior to matching
with two exceptions:  whitespace characters preceded by a backslash are not
removed and whitespace characters within character classes are not removed. 
This can be used, for example to break up long regex' into readable lines.

Examples:
fn:matches("helloworld", "hello world", "x") returns true
fn:matches("helloworld", "hello[ ]world", "x") returns false
fn:matches("hello world", "hello\ sworld", "x") returns false
fn:matches("hello world", "hello\sworld", "x") returns true
