+CLASS net/minecraft/resources/Identifier
+	COMMENT `Identifier`s are used in Minecraft's code to identify a resource's location. 
+	COMMENT To avoid ambiguity, they consist of a namespace representing the creator of the resource and the path to the resource. 
+	COMMENT When converted to a string, the namespace and path are combined becoming `namespace:path`.
+	METHOD assertValidPath (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
+		COMMENT @throws IdentifierException if the path contains a non `[a-z0-9/._-]` character.
+	METHOD fromNamespaceAndPath (Ljava/lang/String;Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT Creates an identifier from a namespace and a path.
+		COMMENT @param namespace the namespace, restricted to `[a-z0-9_.-]`.
+		COMMENT @param path the path, restricted to `[a-z0-9/._-]`
+		COMMENT @return an `Identifier` created from the namespace and path.
+		COMMENT @throws IdentifierException if either string contains an invalid character.
+	METHOD toLanguageKey ()Ljava/lang/String;
+		COMMENT @return A translation key in the format `namespace.path`.
+	METHOD toLanguageKey (Ljava/lang/String;)Ljava/lang/String;
+		COMMENT @return A translation key in the format `prefix.namespace.path`.
+	METHOD toLanguageKey (Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;
+		COMMENT @return A translation key in the format `prefix.namespace.path.suffix`.
+	METHOD toShortLanguageKey ()Ljava/lang/String;
+		COMMENT @return A translation key in the format `namespace.path`. If the namespace is `minecraft`, the translation key is shortened to `path`.
+	METHOD tryBuild (Ljava/lang/String;Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT Creates an `Identifier` from a namespace and a path.
+		COMMENT @param namespace the namespace, restricted to `[a-z0-9_.-]`.
+		COMMENT @param path the path, restricted to `[a-z0-9/._-]`
+		COMMENT @return an `Identifier` created from the namespace and path, or `null` if either string contains an invalid character.
+	METHOD withDefaultNamespace (Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT Creates an `Identifier` with the namespace set to [DEFAULT_NAMESPACE].
+		COMMENT @param path the path, restricted to `[a-z0-9/._-]`
+	METHOD withPath (Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT @param newPath the path, restricted to `[a-z0-9/._-]`
+		COMMENT @return a new `Identifier` with the same namespace and a different path.
+	METHOD withPath (Ljava/util/function/UnaryOperator;)Lnet/minecraft/resources/Identifier;
+		COMMENT @param modifier a modifier to prepend to the existing path, with the result restricted to `[a-z0-9/._-]`
+		COMMENT @return creates a new `Identifier` with the same namespace and a different path.
+	METHOD withPrefix (Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT @param prefix a string to prepend to the existing path, restricted to `[a-z0-9/._-]`
+		COMMENT @return a new `Identifier` with the same namespace and a different path.
+	METHOD withSuffix (Ljava/lang/String;)Lnet/minecraft/resources/Identifier;
+		COMMENT @param suffix a string to append to the existing path, restricted to `[a-z0-9/._-]`
+		COMMENT @return a new `Identifier` with the same namespace and a different path.
