Technical Summary Canonical XML specifies a standard serialization of XML that, when applied to a subdocument, includes the subdocument's ancestor context including all of the namespace declarations and attributes in the "xml:" namespace. However, some applications require a method which, to the extent practical, excludes ancestor context from a canonicalized subdocument. For example, one might require a digital signature over an XML payload (subdocument) in an XML message that will not break when that subdocument is removed from its original message or inserted into a different context. This requirement is satisfied by Exclusive XML Canonicalization. Working Group Summary This document is the W3C (World Wide Web Consortium) Exclusive Canonicalization Recommendation. This document has been reviewed by W3C Members and other interested parties, including the IETF XMLDSIG Working Group. Canonicalization is an important step in the process of digitally signing an XML document. Protocol Quality This document was reviewed by Russell Housley for the IESG.
