To improve debuggability of invalid instances, I added two fields schema_pointer and schema_pointer_history to error result.
schema_pointer
JSON Pointer string pointing to subtree of given JSON Schema where error occur.
schema_pointer_history
Arrayref of JSON Pointer string. When $ref is used, schema_pointer can be nested.
In that case, schema_pointer holds the latest (deepest) one and
schema_pointer_history stores others.
