This Recommendation | International Standard specifies four (canonical Fast Infoset) algorithms that can be used in the application of W3C XML Signature (and provides URIs for them). It also specifies application-level extensions to the W3C XML Encryption processing rules for the encryption of part of an XML infoset (see 8.1) serialized as a fast infoset document and for the decryption of an encrypted part (see 8.3) that was serialized as a fast infoset document. The use of any resulting W3C XML Signature information items or W3C XML Encryption information items is not within the scope of this Recommendation | International Standard.
