<< Before comparing INFO URIs they should be normalized by applying the standard INFO normalization rules (lowercasing the "scheme" and "namespace" components, unescaping non-reserved characters and uppercasing any %-escaped characters that remain). In the example below four unnormalized forms (Step A), are reduced to normalized forms (Step B). (Subsequent normalization steps are not shown as they would be namespace specific.) The Registry may be consulted for namespace-specific rules on case normalization and punctuation normalization. If these namespace-specific rules are available INFO URIs may be reduced to a unique canonical form. Step A - Unnormalized Forms U1.
