------------------------------------------------------------
This was implemented in r818958 (the same day the ticket was filed) as
RegexPatternMatcher, selectable with struts.patternMatcher=regex, and shipped
in 2.2.1. Both forms from the description are supported, the plain named
parameter and the named parameter with a regular expression, and covered by
RegexPatternMatcherTest. Documented under "Advanced Wildcards" on the Wildcard
Mappings page. Closing as Fixed.

> The regular expressions will follow the syntax of JAX-RS. They can be like
> {{\{PARAM_NAME\}}} or {{\{PARAM_NAME:REGEX\}}}. For example:
> {code:xml}
> <package name="regex" extends="struts-default" namespace="/">
> <action name="/{bio:.+}/test/{name}"
> class="org.apache.struts2.showcase.UITagExample">
> <result>/tags/ui/example.jsp</result>
> </action>
> </package>

> <package name="regex2" extends="struts-default" namespace="/superurl">
> <action name="/{bio:.+}/test/{name}"
