Route parameters define a fixed value associate with a qualified name.
Routing: route parameters allow the controller to distinguish branches easily and route the request accordingly.
Rendering: the system will select a route to render an URL if all route parameters are always matched.
Example:
<route path="/foo">
<route-param qname="gtn:handler">
<value>portal</value>
</route-param>
</route>
This configuration matches the request path "/foo" to the map (gtn:handler=portal). Conversely, it renders the (gtn:handler=portal) map as the "/foo" URL. This example shows two concepts:
exact path matching ("/foo")
route parameters ("gtn:handler")
