All changes in 2.1 schemas are backward-compatible with valid UBL 2.0 instances. Changes include:

• the addition of new elements and attributes;
• changes in cardinality from 1 to 0..1 (i.e., making a formerly required element optional);
• changes in cardinality from 0..1 to 0..n (i.e., allowing an unlimited number of occurrences instead of just one);
• corrections to Dictionary Entry Names (DENs).
