I once had a problem.
I thought: "Oh, I know: I'll just use XML!"
Now I had two problems.
I recommend reading all of the 4+ rated comments. Lots of good stuff
and still a very controversial topic. IMO, I don't think that XML is
exclusive to object or relational databases, but rather a bridge
mechanism between the two.

No, I don't think it is really a good idea to stop being open to ideas
about what sorts of information is important to have about plants and
other elements in the database. Nor do I think that the current
schema is optimal and it has a way to go before being "fully
normalized". I do see a point where the schema matures in the sense
that we really don't change it much, but at this point I don't think
what we have still needs a lot of work.
