Should we deprecate the viade:points properties?

[labra]

If we opt to represent routes using the GPX format, maybe we should deprecate the viade:points property that contained a list of points. Tha functionality can be covered by the viade:gpx property.

The viade:gpx property uses a closed list again(:wptTypeList). I'm talking about the problem of closed lists in #20
