+schema resources. ### IRI comparison for identity tokens
+
+When IRIs are used as **identity tokens** (not locators), implementations **MUST use Simple String Comparison** as defined in RFC 3987 section 5.3.1.  
+Normalization or scheme-based comparison is **not required** in this context.
+
+Example:
+
+- `https://example.com/schema/α`  
+- `https://example.com/schema/α`  
+
+These two IRIs are considered identical only if their strings match exactly, without performing additional normalization.

 Several keywords can accept a relative IRI reference, or a value
 used to construct a relative IRI reference. For these keywords, it is necessary
