Router parameter
If router has no parameters,
<router router_id="2" description="quickest">
<parameters>
<navigation_lines file="routing_obst.xml" />
</parameters>
</router>
than one should uncomment the navigation_lines
-tag. Intuitively, I would say a user will uncomment the parameters
-tag.
That leads to problems in parsing. For example in GlobalRouter.cpp
this line should not assume the existence of the parameters
-tag
if (e->FirstChild("parameters")->FirstChildElement("navigation_lines"))
