    - Adding a new "dateLastModified" attribute to XML dictionaries that will help consumers and producers of NAACCR XML determine if they are using the latest release of an XML dictionary.
    - Further clarification in the specifications document that Default user-defined dictionaries are only applicable for NAACCR v21 and prior.
