Snowflake doesn't have to guess, they know the structure of OSM

this stuff... or at least enough understanding of topology to
recognize it when we see it and build simple features with link
attributes that refer correctly to each other's identifiers.
Since this kind of GML only comes around rarely, simply building
purpose-built importers (ala snowflake) case-by-case is almost the
preferred approach.
If this is correct, it would be very helpful if this information was
included in the documentation of the GML parsers in geotools. That
would have made it clear that we were (probably) wasting our time
attempting to use that code.
cheers,
Vince.
