Minor Use case 1 : Import
I have an XSD Schema that is generated by some tools.
I want Nuxeo to use this schema : I would like to import it inside Nuxeo Studio.
Schema inside Nuxeo Studio should be read only, since the schema is generated by external tools.
Use case 2 : Init
I have an XSD Schema that I started working on.
Now I switched to Nuxeo Studio and would like to finish the work.
So I would like to initialize a Studio schema from my XSD, then I will finish the work inside Studio.
Use case 3 : Ref
I have an XSD schema that I created by some ways.
I deploy it inside Nuxeo via a custom plugin.
But I would like Studio to be "aware" of this schema so that I can create Layouts using this schema.
