#### BIP380 Descriptor Backup Content
When `CONTENT` is `TYPE = 0x01` with `DATA = 0x017c` (BIP380), `PLAINTEXT`
is UTF-8 encoded BIP380 descriptor backup content. It is either:
- A text descriptor backup document.
- A JSON descriptor backup document, if the first character is `{`.
is a UTF-8 JSON descriptor backup document. A bare descriptor string is not a
valid document.
Test vectors are in
[`bip380_descriptor_backup.txt`](./bip-0138/test_vectors/bip380_descriptor_backup.txt)
and
[`bip380_descriptor_backup.json`](./bip-0138/test_vectors/bip380_descriptor_backup.json).
Descriptor strings MUST NOT contain private key material and SHOULD include a
checksum.
##### Text Descriptor Backup Documents
A text descriptor backup document contains one BIP380 output script descriptor
per line. Empty lines and lines starting with `#` MUST be ignored. Each
descriptor MUST use BIP389 multipath key expressions, where `/<0;1>` means
receive and change, respectively.
##### JSON Descriptor Backup Documents
The descriptor backup document is a JSON object with the following fields:
