type: path
file:
description:
- The name of the file to be create on the remote device for downloading.
- When C(binary) is set to C(no) the ASM policy will be in XML format.
inline:

- The policy can be be retrieved in playbook C(result) dictionary under C(inline_policy) key.
type: bool
compact:
description:
- If C(yes), only the ASM policy custom settings will be exported.
- Only applies to XML type ASM policy exports.
type: bool
base64:
description:
- If C(yes), the returned C(inline) ASM policy content will be Base64 encoded.
- Only applies to C(inline) ASM policy exports.
type: bool
binary:
description:
- If C(yes), the exported ASM policy will be in binary format.
- Only applies to C(file) ASM policy exports.
type: bool
