I guess what I want to know is whether there should to be a
distinction between 'normal' sequence annotation (comments,
references, and so on) and annotation that could be best described as
position-specific (like RNA or protein structural annotation). The
current meta implementation is for sequence data only; I felt it
would be nice to have a generic implementation that would be
applicable to any object data.
