Thank you for this proposal on XML Encryption references.

I have two suggested changes:

1. move RIPEMD-160 reference to normative section

Section 5.8.5 refers to RIPEMD-160 as key agreement message digest  
method. There is a link to the reference in this section.

2. Move MIME reference to normative section

The optional MimeType reference is defined in terms of mime types, in  
section 3.1, The EncryptedType Element, also with a link to the  
reference.

http://www.w3.org/2008/xmlsec/Drafts/xmlenc-core-11/Overview.htm#sec-EncryptedType

3. I agree that HMAC is not directly referenced and think it should  
be, in two places

Section 5.4.2 PBKDF2 change

" It is RECOMMENDED to use HMAC-SHA256 as the PRF algorithm (see [XML- 
DSIG])."

to

" It is RECOMMENDED to use HMAC-SHA256 as the PRF algorithm (see [XML- 
DSIG], [HMAC])."

and

Section 5.8 Message Digest, change

"and in connection with the HMAC message authentication code method as  
described in [XML-DSIG]."
to
"and in connection with the HMAC message authentication code method  
[HMAC] as described in [XML-DSIG]."
