your are correct this is quite amazing! I suggest duplicating the psi mod term 'half cystine' : 'a protein modification that is effectively either one half of a cystine cross-link, or a cysteine residue with one hydrogen atom or proton removed'
This is a temporary solution waiting for a formal mecanism to import terms from CV and ontology different from PSI-MI , as in requets 1582888 (5 prime overhang and 3 prime overhang -> use sequence ontology)

Amazingly enough disulfide bond didn't make it into the biological feature list so it is, at the moment, possible to specify that two proteins are kept together by S-S bridge but it is NOT possible to specify what is the location of this bridge :o(
can we have a disulfide bridge added as a biological feature ? examples abound. the one which triggered the request is PMID: 17098195
