# ArgumentDeclaration

one argument of a kind of action, and where its value may come from

[figure: ArgumentDeclaration is a value at none scope. The drawing shows its fields and the objects that they point at.]

| property | value |
|---|---|
| kind | value |
| scope | none |
| key | none |
| store | none |
| family | sources |



## Fields


| field | type | required | note |
|---|---|---|---|
| `name` | `text` | yes |  |
| `type` | `text` | yes |  |
| `may_come_from` | `one of the record by id \| a definition \| a person's own words \| a model's answer never` | yes |  |



## Routes that use it
No route takes or returns ArgumentDeclaration directly. The record holds it, and the objects that point at it reach it.
