Add xsd (XML Schema) generator

[cmungall]

indirectly, from a question from @johanneswerner to NMDC

Are there plans to write an xml-schema adapter?

I don't think this is in the critical path for the current linkml plans, but we would welcome any community contribution here

one possibility is linkml->jsonschema->xsd, but the latter step does not seem well supported:

I like to ask if there was any more discussions or work done in the direction to support also XSD as a generator?

We plan to use LinkML in a Standardisation body, and the path to also generate at least XSD, and better also translate from other Data representations to and from XML itself would be an important part.

Currently we see if we can contribute the necessary work, and therefor we like to know what the current status is.
