Section 7.3.2 says:

   Length (16 bits): indicates the total length of the TLV in octets and
   MUST be greater than 0.  The TLV MUST be zero-padded so that the TLV
   is 4-octet aligned.

It should say:

   Length (16 bits): indicates the length of the value portion of the 
   TLV in octets and MUST be greater than 0.  The TLV MUST be zero-
   padded so that the TLV is 4-octet aligned.

Notes:

The "total length of the TLV" is incorrect, as in PCEP the TLV formatting is as per RFC 5440 which requires the length to be of the value portion only. The other text such as "MUST be greater than 0", the padding rules along with "without a NULL terminator" also point to the fact that the intention of the authors/WG was not "total" (and it is simply a mistake).
