// Variant 1 UUIDs, nowadays the most common variant, are encoded in a
// big-endian format.
// For example, 00112233-4455-6677-8899-aabbccddeeff is encoded as the bytes
// 00 11 22 33 44 55 66 77 88 99 aa bb cc dd ee ff
//
// Variant 2 UUIDs, historically used in Microsoft's COM/OLE libraries, use a
// mixed-endian format, whereby the first three components of the UUID are
// little-endian, and the last two are big-endian.
// For example, 00112233-4455-6677-8899-aabbccddeeff is encoded as the bytes
// 33 22 11 00 55 44 77 66 88 99 aa bb cc dd ee ff.

// Note: Only Variant 2 UUIDs are tested.
