Do not use this seed to hold real monies; they could disappear immediately!

  3: "Yinmn Blue Acid Exam",
  4: "This is our standard 128-bit test seed. However, this version of it has a very long note. Why? The object is to force the creation of an animated GIF, which demonstrates the power of URs, not just to allow for the self-identification of information, but also to do so in a way the integrates well with QR codes, creating an animated QR when the data would otherwise be too long for a static QR. To force that to happen, this note was made to be over 500 characters long, which is a lot of data for a QR, which maxes out at about 4,000 alphanumeric characters, but which gets very hard to read (especially from a phone) before that."

Appendix: Standard Process for Creating Test Vectors:

The following process, which can be used for all test vector creation, using a detailed ur:seed as an example.

Write the JSON vector using BCR-2020-006 as reference. Place the hex seed in map element #1, and then optionally place a creation date in element #2, a name in element #3, and a note in element #4.
```
{
  1: h'59f2293a5bce7d4de59e71b4207ac5d2',
  2: 1(1645539742),
  3: "Yinmn Blue Acid Exam",
  4: "This is our standard 128-bit test seed."
}
```

Encode the JSON with CBOR Playground. First test it with full description, then check “plain text” to just produce the hex.

Use bytewords with hex input and minimal output to produce the UR body.
