   This note describes the eXtended Merkle Signature Scheme (XMSS), a
   hash-based digital signature system.  It follows existing
   descriptions in scientific literature.  The note specifies the WOTS+
   one-time signature scheme, a single-tree (XMSS) and a multi-tree
   variant (XMSS^MT) of XMSS.  Both variants use WOTS+ as a main
   building block.  XMSS provides cryptographic digital signatures
   without relying on the conjectured hardness of mathematical problems.
   Instead, it is proven that it only relies on the properties of
   cryptographic hash functions.  XMSS provides strong security
   guarantees and is even secure when the collision resistance of the
   underlying hash function is broken.  It is suitable for compact
   implementations, relatively simple to implement, and naturally
   resists side-channel attacks.  Unlike most other signature systems,
   hash-based signatures can withstand so far known attacks using
   quantum computers.
