In order to match dot(.) or comma (,) the expression [\.,] is enough. There
is no reason to escape the comma itself or to put comma as an indicator of
OR
in the regex. The valid escapes are given in [1].

Schema Pattern Question
Please respond to
xerces-j-user
I have found when entering a regular expression pattern that I have to
escape back slashes when using Xerces-j. For example <xsd:pattern
value="[\\.,\\,]"/> to match dot (.) or comma (,). I would have thought
that "[\.,\,]" would work. I can understand why I would have to do this
in a java.lang.String but it seems like the implementation should not
show through here. Am I doing something wrong? The error says "this
expression is not supported in the current option setting" -- should I
change some option setting?
Thanks,
David Morris
