##### SUMMARY
include_role parameter *public* description: "... vars and defaults are exposed to the playbook." The variables are not exposed to other plays in a playbook.
##### ISSUE TYPE
- Documentation Report

##### COMPONENT NAME

include_role

##### ANSIBLE VERSION

devel

##### CONFIGURATION

No changes. All defaults.

##### OS / ENVIRONMENT

> cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.1 LTS"

##### STEPS TO REPRODUCE

https://gist.github.com/vbotka/8a435e917bccc655e08cbd11b43eabd4

##### EXPECTED RESULTS

The documentation says "exposed to the playbook". This evokes the expectation the variables are available to other plays in the playbook.

```paste below
PLAY [two] ***********************************************************************************

TASK [role-two : debug] **********************************************************************
ok: [two] => {
    "variable_one": "Role One Variable"
}

PLAY [one] ***********************************************************************************

TASK [role-two : debug] **********************************************************************
ok: [one] => {
    "variable_one": "Role One Variable"
}
```

##### ACTUAL RESULTS

The variables are not available to other plays in the playbook.

```paste below
PLAY [two] ***********************************************************************************

TASK [role-two : debug] **********************************************************************
ok: [two] => {
    "variable_one": "VARIABLE IS NOT DEFINED!"
}

PLAY [one] ***********************************************************************************

TASK [role-two : debug] **********************************************************************
ok: [one] => {
    "variable_one": "VARIABLE IS NOT DEFINED!"
}
```

    description:
      - File to load from a role's C(handlers/) directory.
    type: str
    default: main
    version_added: '2.8'
notes:
  - Handlers are made available to the whole play.
  - Before Ansible 2.4, as with C(include), this task could be static or dynamic, If static, it implied that it won't
    need templating, loops or conditionals and will show included tasks in the C(--list) options. Ansible would try to
    autodetect what is needed, but you can set C(static) to C(yes) or C(no) at task level to control this.
  - After Ansible 2.4, you can use M(ansible.builtin.import_role) for C(static) behaviour and this action for C(dynamic) one.
