However, this serves only to exclude '^' and '$' as normal characters (and thereby create escapes for them) but it does not make them part of the regular expression syntax. Using the modified rules of XML Schema part 2, there is no way to derive that, for example, '^abc' is a regular expression. I think the anchors are supposed to enter the regular expression rules at the precedence level of rule [9] atom. Probably a modification of this rule is needed. 6494 1 ashok.malhotra 2005-09-27 15:22:28 +0000 The joint WGs discussed this on 9/27 and decided that no change was needed as production [11] handles the two metacharacters that we introduce.
