Change to HTTPS for schema downloads

[David Goodenough <david.goodenough@broadwellmanor.co.uk>]

I just came across an article in the Register https://go.theregister.com/feed/www.theregister.com/2022/08/22/w3cs_transition_https/ saying that w3c are transitioning from http to https.

Looking at the UBL schemas, I notice that there are still http: references present.

So for instance from the Bill of Lading xsd file there is:-

=======================================

            attributeFormDefault="unqualified"

            version="2.3">

=======================================

Note the xmlns:xsd="http://www.w3.org/2001/XMLSchema" which should read:-

xmlns:xsd:="https://www.w3.org/2001/XMLSchema"

Is there a plan to change this?  And what is the plan for backward compatibility?
