Description:

xmlschema library cannot load schemas from certain URLs due to local issuer certificate.

To reproduce:

Simply load a schema from URI using either XMLSchema11 or XMLSchema10 xmlschema.XMLSchema11('https://xbrl.fasb.org/srt/2023/elts/srt-2023.xsd')

Expected behavior:

The schema should be successfully loaded from URL.

Actualy behavior:

xmlschema library reports the following error:

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)>

Environment:

Hi, sorry but this seems to be a problem in your local environment, that probably doesn't see the root certificates, because the website xbrl.fasb.org has a valid certificate renewed weeks ago, and my checks don't show me any problems on loading that schema from remote

So you have to find a solution for your environment starting from the urllib.error.URLError that is returned.
