[Routing] Route format

Hi Tim,

Thanks for your answer.

The route calculation is already done, I have an ordered list of nodes, relations and links ("extracts" of a way) describing the path to follow.
I am looking for specifications describing a route. Ad example:
<route>
   <node ... />
   <link ... />
   <node ... />
   <link ... />
   <relation ... />
   <link ... />
   <node ... />
   ...
</route> 

I have tried to find something like that on google, but unsuccessfully. Maybe I have missed a point...

Thanks,

Audrey
