Section 3.2 says:

   b.  Set:

          V = 0x01 0x01 0x01 ... 0x01

       such that the length of V, in bits, is equal to 8*ceil(hlen/8).
:
:
   c.  Set:

          K = 0x00 0x00 0x00 ... 0x00

       such that the length of K, in bits, is equal to 8*ceil(hlen/8).

It should say:

   b.  Set:

          V = 0x010101...01

       such that the length of V, in bits, is equal to 8*ceil(hlen/8).

   c.  Set:

          K = 0x000000...00

       such that the length of K, in bits, is equal to 8*ceil(hlen/8).

Notes:

Hrmonize the notations in 3.2 and A.1.1, where the hex string q is denoted as
0x4000000000000000000020108A2E0CC0D99F8A5EF
and not as
0x40 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x20 0x10 0x8A 0x2E 0x0C 0xC0 0x0D 0x99 0xF8 0xA5 0xEF.
