Hi Patrick,

Thanks for resending this to xsd-users.

XSD does not support HTTPS protocol in URLs (HTTP and FTP are supported if
you build Xerces-C++ with network enabled). You will need to use a third-
party library for HTTPS. Libcurl[1] seems like a good candidate.

You can read the data using the third-party library and then present it
to XSD as either std::istream or xercesc::InputSource. If the file is
not very big you can also read it in as a string and then parse it using
std::istringstream.
