Well, the goal for right now is a lot more modest than a general
database architecture -- I'm just using database terminology with our
parse tree representation because treating it as a (hierarchical)
database turned out to have some conceptual benefits.

Conceivably, we might do some real database-y things down the road to
support things like distributed editing, but that's a long way away
yet...

Even then, I'm not sure GnomeDB would be a good fit, since GnomeDB is
designed for relational rather than hierarchical data.

Also, there are some special requirements, like a commit operation that
returns a log fragment which later can be rewound/replayed to undo or
redo the transaction (this is used for undo/redo of operations that
affect the parse tree), and fine-grained constraints and change
notifications.
