Look at the proposal and note that it is a proposed replacement to the 2003 agreement:  http://www.loc.gov/z3950/agency/agree/request-xml.html 

It was then that 1.2.840.10003.5.112  was introduced  for XML records whose schema can be identified by  an accompanying ElementSetName.

This seems to me a bit frivolous, does the client really care whether the server says the record is 110 (xml) or 112 (xml)?  

The purpose of this (current) proposal is twofold: (1) to codify current practice (and in fact, practice that has been in place for several years) and (2) to put in place a policy regarding the assignment of identifiers for future schemas used by Z39.50.

With respect to the first, what is the current practice?
