example is clearly not a bitmap

[dkg]

One example S-Expression in the document is (4:icon[12:image/bitmap]9:xxxxxxxxx)

But a series of 9 x octets is clearly not actually an image/bitmap object. Why include a broken example in the document? either put an actual image/bitmap bytestream here, or give it a different display hint.

Do you have any particular suggestion? By the way, it looks like "bitmap" is not actually valid, see https://www.iana.org/assignments/media-types/media-types.xhtml#image
