Thanks for your clarifications, Richard!
I now understand that GML will not help me any further.
For two shapefiles which I commonly use (soil map of Belgium and map of
biological value), I made .qml legends myself now.
Since the 2.6 release this is much easier because of the colour picker
tool. Nice feature!
I sent a message to geopunt whether they can add these .qml legends to
their downloads.
I don't think they will do this (as this would require them to check
these files for consistency with the original). Let's see.
Cheers!

As far as I know, I cannot use these with Qgis (.qml or .SLD files needed).

should be able to open them.
Well you can off course open the shapefiles, but you will not have the
same styling as is defined in lyr/avl files. You could off course try to
mimic that style and sent qml files to Geopunt :-)
When I try to open .gml files, I get a table, no geometry (nothing is
mapped). I have a windows install of Qgis 2.6. Are there any additional
plugins or libraries needed to make this work?
I found in this link (http://www.gdal.org/ogr_formats.html) that read
support needs Xerces or libexpat. Do these come with Qgis install? How
can I check wether I have these or how I should install these?
Opening a gml file is the same as opening a shp file, no styling
included. So it is the data you are after, you could get the shp files.
That said, GML is a tricky beast because so much different constructs
are possible, but normally QGIS (or actually OGR) is able to handle a
lot of those.
I tried it with this GML:
https://downloadagiv.blob.core.windows.net/overstromingsgebieden-en-oeverzones/2014_01/Overstromingsgebieden_en_oeverzones_2014_01_GML.zip
And indeed only get tables and no geometries...
BUT if I use ogr to open them:
ogrinfo -al Ogoz.gml
OGRFeature(Ogoz):15
UIDN (Real) = 16
OIDN (Real) = 16
CODOGOZ (Integer) = 16
NAAMOGOZ (String) = OG Puttenbeek
NUMAC (Real) = 2014035191
ININMRID (String) = 20001
ININMR (String) = Provincie Vlaams-Brabant
OPPERVL (Real) = 17031.46
LENGTE (Real) = 969.01
POLYGON ((138955.079 183000.758,138911.506 182970.395,138897.621
... truncated ...
183007.847,138961.648 183005.335,138955.079 183000.758))
So apparently OGR sees the geometries, but QGIS not ??
Dev's? Any idea about this?
Should we open an issue?

Richard Duivenvoorde
