	 *                                            - @param string   $attribute_name The name of the target attribute.
	 *                                        The callback has a mixed return type; it may return a string to override
	 *                                        the block's original value, null, false to remove an attribute, etc.
	 *     @type string[] $uses_context       Optional. Array of values to add to block `uses_context` needed by the source.
	 * }
	 * @return WP_Block_Bindings_Source|false Source when the registration was successful, or `false` on failure.
