Extend Studio and reuse

Dear CUBA team,
I’m studying ‘extend studio’ and trying to use it in my project. I think it is very useful to reuse UI component between different projects, of course, it will save lots of time. However, I’m wondering if I can package everything into one component and shared with other guys who also want to use it in CUBA studio as I can only find java class and screen descriptor of my new component in the package but the XSD file.
PS. I can’t find any explanation in both documentation and forum.

Thanks for your time.
