	// The query_var is used for direct queries through WP_Query like `new WP_Query( array( 'people'=>$person_name ) )` 
	// and URL queries like `/?people=$person_name`. Setting query_var to false will disable these methods, but you can 
	// still fetch posts with an explicit WP_Query taxonomy query like `WP_Query( array( 'taxonomy'=>'people', 'term'=>$person_name ) )`.

		, 'query_var'			=>	'taxonomy_name' // False to disable the query_var, or set a string as a custom query_var. Default: $taxonomy_name

	);

	// Register the taxonomy with prepared $object_types and $args

	register_taxonomy( 'taxonomy_name', $object_types, $args );

	// To be safe, do this next to make sure post types are attached inside filter callbacks during `parse_request` and `pre_get_posts`

	foreach ( $object_types as $type ) {
		register_taxonomy_for_object_type( 'status', $type );	
	}

what is the use of register_taxonomy_for_object_type( 'status', $type ) ?

I don't get the meaning from line 86 comment.

Thanks!
