Issue meta: Issue sponsor

Capture the issue sponsor in an issue-sponsor element in the issue meta.

issue-meta/issue-sponsor

The issue-sponsor element should come after the issue-title element (if present), and before the pub-date element.

The sponsor captured here must match exactly the sponsor found in the article meta for every article in the issue. See Issue title page.
