Explanation of the output

The following text contains the nodeset of the given Reference before it is canonicalized. There exist four different styles to indicate how a given node is treated.
A node which is in the node set is labeled using the INCLUDED style.
A node which is NOT in the node set is labeled EXCLUDED style.
A namespace which is in the node set AND in the InclusiveNamespaces PrefixList is labeled using the INCLUDEDINCLUSIVENAMESPACE style.
A namespace which is in NOT the node set AND in the InclusiveNamespaces PrefixList is labeled using the INCLUDEDINCLUSIVENAMESPACE style.
