[OASIS Issue Tracker] (ODATA-923) $expand for $metadata to include referenced schemas

[ https://issues.oasis-open.org/browse/ODATA-923?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=62506#comment-62506 ] 

Michael Pizzo commented on ODATA-923:
-------------------------------------

I like the capability, but not sure I like using $expand for this.

What would we put for the value of the $expand? The namespace to be expanded?

Would we support recursive/nested expansion? Based on levels or paths or?

Would this just be returned as a document with multiple <Schema> elements, one for the main document and one for each included document?

> After being able to partition large services into smaller ones using cross-service navigation we might want to support requesting multiple of these small files in one request, similar to expanding an entity and including related entities.
