Getting an error trying to convert http://skjema.geonorge.no/SOSI/produktspesifikasjon/FKB-Ar5/4.6/FKB-Ar546.xsd

$ xsd2pgsql/xsd2pgsql.py FKB-Ar546.xsd
Traceback (most recent call last):

same error with https://www.loc.gov/standards/alto/v3/alto-3-0.xsd

any ideas how to fix this by either modifying the .xsd a bit or fixing the code?

I had the same problem with http://skjema.geonorge.no/SOSI/produktspesifikasjon/Norskvann-Asbuilt/2.2/Asbuilt.xsd
Setting buildTypes('', xsd) solved the problem, for both asbuilt.xsd and FKB-Ar546.xsd, but many of the attributes are missing from the tables.
