[Bioperl-l] accessing optional qualifiers within features?

Hi Ewan,
Thanks for this example - it helped to clear things up.
I notice that filling the array in the example you gave generates
an exception if any of the primary tags do not have at least one tag
value 'note'. I guess it is the expected behaviour here that the
method throws an exception rather than returning a null?

cheers
Sam
