I just re-checked having looked at the data when it first became
available, and there are still no GML Application Schemas in the

Are they available?  Without these, GML parsers cannot find out how the
GML/XML is structured, e.g. which element is actually the Geometry.
That makes the data unusable except in GML parsers that have an
additional - arguably redundant - configuration file.
