XML Encryption 1.1 update for base64 clarity

I have revised the XML Encryption 1.1 editors draft to clarify the note and text related to base64 encoding.

I have changed the base64 note in the algorithms section (section 5) from

[[
*note: Note that the same URI is used to identify base64 both in "encoding" context (e.g. when needed within a CipherValue element) as well as in "transform" context (when identifying a base64 transform)
]]

to

[[
*note: The same URI is used to identify base64 both in "encoding" context (e.g. when used with the Encoding attribute of an EncryptedKey element, see section 3.1 The EncryptedType Element<file:///Materials/Builds/xmlsec2/Drafts/xmlenc-core-11/Overview.src.html#sec-EncryptedType>) as well as in "transform" context (when identifying a base64 transform for a CipherReference, see section 3.3.1 The CipherReference Element<file:///Materials/Builds/xmlsec2/Drafts/xmlenc-core-11/Overview.src.html#sec-CipherReference>).
]]

http://www.w3.org/2008/xmlsec/Drafts/xmlenc-core-11/Overview.html#base64note

For visibility I also added the following to the end of section 3.1:

[[

Encoding is an optional (advisory) attribute which describes the transfer encoding of the data that has been encrypted.

]]

(the previous MimeType paragraph outlines its use in conjunction with MimeType and gives base64 as an example)

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

This should resolve LC-2542

Please indicate any correction or comment on the public list.

(By the way I double checked and the original (current) XML Encryption Recommendation has the same text regarding Encoding and base64 as well as use in the transform).
