Education is separate from Work for the purposes of FSW. They evaluate your education on its own merits. Your job duties must match the majority of those required by the NOC (29) you are applying under. The VO is to determine whether or not you have performed those JD and not whether you have the required education. (I am sure you would NOT be given credit for JD of a doctor or nurse, etc. without the requisite degrees though.)
Here it is stated in the OP 6 Handbook
http://www.cic.gc.ca/english/resources/manuals/op/op06-eng.pdfThe officer must not take into account whether the applicant meets the “Employment requirements” description set forth in the NOC for the occupation(s) listed (R80(3)).
Hope this helps.
