|            |           |
|------------|---------- |
| Message    | uset contains properties, not allowed |
| Module     | [kmc-kmn.KmnCompilerMessages](kmc-kmn.kmncompilermessages) |
| Identifier | `ERROR_UnicodeSetHasProperties` |

The provided uset uses property notation (`\p{…}` or `[:…:]`). LDML
keyboards do not support Unicode properties in usets, because that would
make implementations dependent on a particular version of Unicode. To
resolve this, reformat the uset to avoid the use of properties.
