I really, really, like this idea, especially since it doesn't introduce
any new syntax or complications for the 90% of users that don't need
this. The more we can keep Struts/XWork to simple, internal components,
the easier it will be to worth with both as a user and as a developer.
This would make a nice plugin with default result types for common
situations.

Then, each result selector is given a chance to select a single String.
If a result has when="modern-browser,partial-html",
the each selector will be given a chance to return its "when" token, and
xwork will match them together as AND.
Or, with wildcards ...
<result-type name="selector" class="o.a..d.SelectorResult" >
<param name="matchers" class="o.a.s.d.RoleMatcher">
<param name="matchers" class="o.a.s.d.AgentMatcher">
<param name="wraps" class="o.a.s.d.ServletDispatcherResult>
</result-type>
<action name="*" class="mypackage.{1}">
<result type="selector">/{1}{result-code}{role}{agent}.jsp</result>
<result name="error">/{1}-error.jsp</result>
</action>
Each "matcher" could add a named token into the context, like
"-manager". The selector result could then resolve the wildcard path
and delegate to another Result, like the default ServletDispatcher
Result. The matchers might not inject a token, if it was the default
or didn't apply for some reason.
So, an application using this strategy might have pages named like.
* ViewFoo.jsp
* ViewFoo-netscape4.jsp
* ViewFoo-manager.jsp
* ViewFoo-manager-netscape4.jsp
* ViewFoo-failure.jsp
Of course, this strategy presupposes using something like SiteMesh or
Tiles to provide the standard layout, so that each "page" can just
focus on it's own content.
