I don't think this is known. The read.spss code is taken from code in
PSPP, which was going to be a GNU implementation of SPSS. Judging from
some of the comments in the code, at least part of the format was worked
out from files, not documented.
I haven't run across any problems in using it to read SPSS .sav files, but
most of the ones I have tried were created by the same people and don't
represent independent confirmations.
