Common conflicts
| Intended name | Problem | Better option |
|---|---|---|

label | Reserved block keyword. | displayName, title, _label. |

Example
Avoid:
kind Metric {
value: number
description: string
}
Prefer:
kind Metric {
measure: number
summary: string
}
Use a leading underscore only when the domain term is unavoidable and the underscore will not confuse readers.
