This command line will generate a version of the schema that depends on
the opengis bundle. It also saves a local copy of the schemas it has to
download, in case it's useful to examine them manually.
pyxbgen \
--uri-content-archive-directory downloaded \
--archive-path '&pyxb/bundles/opengis//:+' \
--schema-location
http://www.aixm.aero/gallery/content/public/schema/5.0/AIXM_Features.xsd \
--module test
Note the need to place the archive-path argument in single quotes so the
ampersand that denotes the PyXB installation directory does not get
interpreted as a Unix shell run-in-background operator. This does
assume you've installed either the full PyXB distribution, or have
downloaded the opengis overlay.
Documentation on the archive path capability can be found at
http://pyxb.sourceforge.net/api/pyxb.namespace.archive-module.html#PathEnvironmentVariable
