Trying to parse us-gaap taxonomy xsd, parser throws "namespace for prefix 'xlink' has not been declared"

[ramonchu]

The official US accounting standard XSD schema can't be parsed.
You can download schema on: https://xbrl.fasb.org/us-gaap/2021/us-gaap-2021-01-31.zip

At run time, the parser throws:

java.lang.RuntimeException: Namespace for prefix 'xlink' has not been declared.

Hello,

I've identified the issue, it was related with namespace awareness being disabled by default. I've tried to parse the entire/us-gaap-entryPoint-all-2021-01-31.xsd and it worked. I've deployed a new version, 1.2.0, with the fix.

Thanks for using the library, sometimes it's unexpected to see how this is being used.
