[OSGeo-Standards] Proposal for Open Search Geo extension support of point and line

[Volker Mische]

The problem I see with the draft is, that it is still not updated to 
match the OGC version of it. For example advanced stuff like the type of 
intersection of the geometry is missing.

Cheers,
   Volker
