Chris or Paul may know the history, but I think what constrainttype is 
_supposed_ to do is allow one to distinguish between a copy-level (or 
biblioitem-level?) hold (type 'o') and a title-level hold (type 'a'). 
Or was it meant to be "metabib" (type 'a') versus biblioitem (type 'o')?

However, as near as I can tell, at present 'a' and 'o' holds currently 
behave identically, and the only code that creates holds with a type 
other than 'a' is the serial routing list.  In other words, I'm 99% sure 
that the reservecontraints mechanism doesn't work at all, and is a 
carry-over from 2.x that it may be better to drop.

I would be grateful if anybody with knowledge of the original intent of 
the hold constraint feature could share what they know.

Regards,

Galen
