XML User Dictionary

Thank you to all the registries that have posted their XML user dictionary or a statement that they will not be creating an XML user dictionary to the XML Dictionary Submission Clearinghouse by the October 1, 2021 deadline! And, just a reminder that the XML Data Exchange Workgroup has updated the information on the XML user dictionary website including FAQs. If you need additional help with your XML user dictionary, please post to the NAACCR XML Forum, which is monitored by the XML Data Exchange Workgroup.
