Cayenne 4.2 StringProperty—implement Comparab leProperty?

Hi all.
I've been experimenting a little with Cayenne 4.2. It looks lovely and I can't wait to start using it.

One thing I bumped into is that StringProperty does not implement ComparableProperty. Although I'd personally never design a DB or a system that requires this, I work with a couple of legacy systems that use comparison of string fields ("someString">"otherString" etc.). Doing a little googling seems to show that it's also a bit of a practice and widely supported by DBs.

So… Do you think StringProperty should implement ComparableProperty? I'm torn myself. It feels wrong—but if it's supported by DBs and widely used, perhaps the Cayenne API should allow for that?
