# is all with min max

When attaching `min N`, or `max M`, or both to a declaration, we limit the number of Instances that are expected to be present in a Case.

### Syntax

`VARIABLE is all ONTOLOGY, ROLE_1, ... ROLE_N min N max M`

A match with the name `VARIABLE` is created for an Instance that has the Ontology `ONTOLOGY` and all the roles (`ROLE_1` to `ROLE_N`), and the number of Instances found in the Case are no less than `N` and no more than `M`.

Both `min` and `max` are optional attachments to a declaration. The declaration would still be valid with neither, both or only one of them.

### Examples: min

```python
ps is all Person min 3
```

If there are at least 3 Instances of `Person` in the Case, `ps` will hold a list of at least 3 `Person` Instances.

### Examples: max

```python
ps is all Person max 5
```

If there are at most 5 Instances of `Person` in the Case, `ps` will hold a list of at most 5 `Person` Instances.

### Examples: min and max

```python
ps is all Person min 3 max 5
```

If the number of `Person` Instances in the Case is between, but including 3 and 5, `ps` will hold a list of 3 to 5 `Person` Instances.

### Examples: min, max and Roles

```python
ps is all Person, AccountHolder min 3 max 5
```

If the number of `Person` Instances with the Role `AccountHolder` in the Case is between, but including 3 and 5, `ps` will hold a list of 3 to 5 `Person` Instances.
