Does anyone know whether there is a specification of the GML that
v.out.ogr outputs? I know this is more an OGR question, but I'm not
entirely sure what's responsible for what, with the olayer-named
element and the cat, str1 and label elements, which don't seem to be
GML or OGR since they're in neither namespace.
I mainly want to know the extent of possibilities within each
gml:featureMember, really, since I'm writing a simple parser for this
output.
Particularly the non-namespaced elements (I'll try to find the format
of gml:feats, though an URL would be appreciated), and preferably also
things like if/how multiple categories are handled, what the
difference between a label and if/when there is a str1 or even str2.

Useful to know. I suppose the
gml:outerBoundaryIs gml:LinearRing gml:coordinates
tree structure is always like that too?

How wasteful. I guess I'll have to detect that. Ah well.
Anyhow, thanks. That only really leaves the label/str1 questin, but I
can probably assume it's either/or and work around that.
