Scope changes the meaning of a prefix
A nested declaration can rebind a prefix for its descendants. The report treats each binding in scope rather than assuming one document-wide prefix table.

What this tool does
XML 1.0, bounded, and local
A prefix is only a local alias. The namespace name is the URI bound in scope, and the default namespace applies to unprefixed element names but not ordinary unprefixed attributes.
URI identity matters more than spelling
Two documents can use different prefixes for the same namespace name. Conversion and comparison preserve namespace identity separately from the lexical prefix.
