I'm not at home so I can't re-double-check that I have them in my

Most of the lines are eye candy but the attributes special to the branch are:
device: used to determine if a symbol is "compatible" with a part's
slot (example, not special case)
pinnumber: gets rewritten
pinfunction: used as key into function->pin number map
slotname, slotowner: determines slot/symbol linkage
slotrewrite: names "magic" attribs that get "inherited" from the heavy part
slotmap: defines function->pin number map
