Packaging Extensions with Localization Tables
If you are creating an extension that requires its own localization tokens and values, do the following:
1. Use namespacing conventions for token names.
For more information, see the Localization for Applications section in the Widgets topic.
2. Export localization tables using the token prefix filter set to the correct namespace.
3. Include the exported localization tables in the extension package.
