Fixes #670

@bussec physical_linkage also has a NULL-like value (none), change it to null?

bussec commented 11 months ago

@schristley No, as physical_linkage is x-airr.miairr = essential and thus not nullable. Also, physical_linkage being none has a different meaning ("it is NOT linked") than null ("no information").
