I assume you had a schema to point to.
The GMLAS driver has been tested on a number of fairly complicated models 
(Inspire, CityGML, etc.) as well as Simple Feature ones, but I cannot exclude 
it might fail on some schemas. Or perhaps the structure it generates was too 
complicated (which just reflects the complexity of the original schemas) ?

If GML_ATTRIBUTES_TO_OGR_FIELDS is set, we could probably avoid treating 
xsi:nil as a particular case.
