The current version of MODS is available both through a version specific 
URL ( as well as a 
more generic URL (  Can 
users count on the more generic URL always pointing to the most recent 
version of the MODS schema that is backwards compatible through version 
3.1?  (I believe that there is a break in compatibility between version 
3.0 and 3.1).  Or, to phrase the question a little differently, if a new 
version of the MODS schema was produced that was not backwards 
compatible with versions 3.1-3.3, would it replace the 3.3 schema that 
is now available via the generic URL  I am asking this because of 
its implications for how the schemaLocation in mods instances should be 
set up.
