While the Candidate Recommendation of XML 1.1 only listed changes between 1.1 and 1.0, the Proposed Recommendation integrates the XML 1.0 and 1.1 specifications. While this does make it more difficult to see what has changed between the CR of 1.1 and the PR of 1.1, a version change-marked from XML 1.0 does make it easier to see what XML 1.1 changes overall.

Namespaces in XML 1.1 also integrates itself with Namespaces in XML 1.0, though unfortunately it lacks a change-marked version, so it's difficult to tell what if anything has changed between the CR of Namespaces in XML 1.1 and the PR, as well as between 1.0 and 1.1.
