Hi Peter,
Thanks for this. Unless I'm mistaken, namespace URIs are not required to map
to any resource at all, let alone an XSD. However, the xsd from which I'm
generating the code is at
http://xmlgw.companieshouse.gov.uk/v2-1/schema/Egov_ch-v2-0.xsd.
What is PyXB expecting in its input that could be leading to this? Does it
rely on namespaces naming XSD files?
