[Annotation] [Evidence] Fwd: ISS/ISA from Southerns?

I like the idea of using IPI.
At the moment all experimental annotations should be able to be
described by one of the child codes of EXP, the only annotations which
directly use this code are those which do meet the criteria of the child
experimental codes, but cannot be retrofitted by the submitting group.
It might be nice to keep it this way, rather than allow EXP to be used
for undocumented experimental methods - otherwise EXP could potentially
end up as a dumping ground for a diverse range of annotations where the
curator is not sure which of the child experimental codes is appropriate.
