Sevencs succeed in many other aspects where others fail.
For example, they will actually parse and show older Netherlands chart
data (I still have a few cells from a year ago), which encoded polygon
edges using multiple SG2D fields, rather than a single SG2D field with
multiple values. Not only th

You can't. Because of the meaning of the 'A' in GDAL, a VRT is seen as a
single raster for any user of GDAL API. A dedicated function should be
created in QGIS to parse the VRT XML and make sense of it for what you wish.
