Dissertation: should it be moved?

The Dissertation type is something of an anomaly for written works. It's linked in to the Education compound-value type, and gets its information about the author and university, and arguably date written from there.  All other types of written work get author and date properties from the Written Work type, which also has useful properties like "subject".  I'd like this type to be more integrated with the rest of the written word. Once solution would simply be to add Written Work as an included type, but that would result in two Author properties.

What I'd like to propose is to uncouple it from the Education CVT (which is getting pretty crowded anyway); give it an included type of Written Work; and create a new property for University. Additional properties could also be added, if needed.

Thoughts?
