Description:
------------
The documentation for referencing a named pattern for recursion is incorrect.

From the documentation at http://us.php.net/manual/en/reference.pcre.pattern.syntax.php:
----
Since PHP 4.3.3, (?1), (?2) and so on can be used for recursive subpatterns too. It is also possible to use named subpatterns: (?P<name>foo). 
----

Subpatterns are referenced for recursion as (P?>name), not (?P<name>foo).

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

This already was fixed.
