I've been reading through the documents again and have noticed some typos.

XML Encryption Requirements (http://www.w3.org/TR/xml-encryption-req)

3. Requirements
  3. Processing
    8. If a document is (partially) encrpyted

XML Encryption Syntax and Processing (http://www.w3.org/TR/xmlenc-core/)

5.2 Block Encryption Algorithms
    Paragraph 1:
      Since the data being encrypted is an arbitrary number of octets, 
      it may not be a multiple of the block size. This is solved by 
      padding the plain text up to the block size before encryption 
      and unpadding after decrytion.

5.3 Stream Encryption Algorithms
  Paragraph 3:
    No specific steam

5.4 Key Transport
  Paragraph 2:
    (Key Transport algorithms may optionally be used to encrypt data in
    which case they appear directly as the Algorithm attriubte

5.6.2 CMS Triple DES Key Wrap
  Paragraph 3:
    An example of a TRIPLEDES Key Wrap EncryptionMethod element is a as
s/is a as/is as/

  Step 6. Left TEMP2 = IV || TEMP1.

5.6.3 AES KeyWrap
  Paragraph 4:
    Assume tha ...

    ... the data to be wrapped consists of N 64-bit data blocks
    denoted P(1), P(2), P(3) ... P(N). The result of wrapping will be N+1
    64-bit blocks denoted C(0), C(1), C(2), ... C(N). They

  Paragraph 6:
    If N is 1, a single AES operation is performed for wrap or unwrap. If
    N>1, then 6*N AES operations are performed for warp

Murphy's Law dictates that any e-mail regarding typos will in itself
contain additional typos!  Please forgive these.
