Thanks for reviewing the best practices document

I believe your comment is in the following document you uploaded:
http://www.w3.org/2008/xmlsec/Drafts/best-practices/comments-bhill-jcc.html
The comment is in section 2.1 before the first best practice and is:
"[jcc: I think that best practices 1 and 3 overlap somehow, as they  
seem to mix two concepts: "authentication" of the signer, and trust in  
that signer. I would also say that the header of best practice 1 is a  
does not completely match the content, as its content actually speaks  
of trust not of authentication. My proposal would be to change the  
header of best practice 1 to: "Mitigate denial of service attacks by  
executing potentially dangerous operations only after establishing  
trust in the signer key". After that I would suppress best practice  
3. ]"
Thus in the latest editors draft
http://www.w3.org/2007/xmlsec/Drafts/xmldsig-bestpractices/
I believe your proposal is:
1. change the title of best practice 1 to: "Mitigate denial of service  
attacks by executing potentially dangerous operations only after  
establishing trust in the signer key"
2. remove best practice 2:  Best Practice 2: Establish trust in the  
verification/validation key.
However I think the intent of best practice 1 was to indicate  
verification of the signature on SignedInfo before validating  
references and #2 was to also remind to verify keys, thus I suggest we  
do not make the change you suggest, since #1 did include signature  
verification and #2 is important to call out the importance of key  
verification.
regards, Frederick
