[Bioperl-l] Bio::AnnotatableI vs Bio::FeatureHolderI

[Michael Kiwala]

Are Bio::AnnotatableI and Bio::FeatureHolderI competing interfaces?

I get the impression they are designed to do similar things.  If so is 
one deprecated and the other preferred?

If their responsibilities are orthogonal to each other, what sorts of 
tasks are suited to each?

Thanks,
Michael
