I used to know all about this... IIRC the SwissProt format READMEs are
the best place to go to work out what is what. Also the module
documentation for the SwissKnife parser was good.

I know BioPerl has a lot of modules for handling generic 'sequence
features'. You may try looking at BioJava to see if there is something
similar.

All the best,
