The order of route declaration is important as it affects how rules are matched. Sometimes, the same request could be matched by several routes and the routing table is ambiguous.

<route path="/foo">

  <route-param qname="gtn:handler">

    <value>portal</value>

  </route-param>

</route>

<route path="/{gtn:path}">

  <path-param encoding="preserve-path" qname="gtn:path">

    <pattern>.*</pattern>

  </path-param>

</route>

In that case, the request path "/foo" will always be matched by the first rule before the second rule. This can be misleading since the map (gtn:path=foo) would be rendered as "/foo" and would not be matched by the first rule. Such ambiguity can happen, it can be desirable or not.
