This can also be painful to parse for some who wish to process
GetFeatureInfo responses.  

Suggest to abstract the GetFeatureInfo reponse construct to not include data
as element names and / or attributes, yet values of said.

i.e.

<Layer name="Groningen kust vlakken 2002">
 <Feature>
 ...
 </Feature>
</Layer>
