meta-informations

Unfortunately, attributes do not allow to express structured information, and they cannot have meta-informations attached to them.

You want to represent a document, with reviewers, publication dates and authors (those are meta-informations, right?) as well as content (the actual text being stored).

However, there exists meta-informations about people (name, title) and dates (calendar).

Where do we store structured meta-informations about attributes?

An so, peoples are not just meta-informations, but tags with nested children and you must have a "root" element around your document, and a special list of "peoples".

Besides, you failed to notice that you had <author> tags, which precisely goes against your idea that there should be a place for "meta-data" and a place for "data": effectively, authors are now part of the content of the document, and are not only meta-informations.
