If use of a term is discontinued, it is good practice to retain it as a 
non-preferred term, with a USE pointer to the term or combination of 
terms that should be used in future for the concept that it represented. 
A history note should indicate when it was used for indexing.

I don't think that you need to distinguish between "deprecated" and 
"non-preferred" terms, which you would express as altLabels. As you have 
noted, you do however have to handle combinations such as:

"physics education  USE  physics  AND  education"
