1 This library supports full W3C XML Schema regular expressions inclusive all
2 Unicode character sets and blocks. The complete grammar can be found under
3 <http://www.w3.org/TR/xmlschema11-2/#regexs>. It is implemented by the
4 technique of derivations of regular expressions. The W3C syntax is extended
5 to support not only union of regular sets, but also intersection, set
6 difference, exor. Matching of subexpressions is also supported.
7 The library can be used for constricting lightweight scanners and tokenizers.
8 It is a standalone library, no external regex libraries are used.
9 This package is a substitute for the old regex-xmlschema package.
