Documentation or code bug in register_taxonomy_for_object_type function (wp-includes/taxonomy.php)

[transom]

The documentation indicates that the post_type can be an array or a string.

However, the code passes the post_type to get_post_type_object without change and that function expects a string (ouch)

So the choices are: change the documentation or loop over an array.

If we loop, what does returning the bool true/false mean? We added all the post_types or just some of the post_types

Happy to provide a diff with feedback on direction

Looking at the function, seems that the documentation should just be corrected.

Agreed.

​Codex description is correct, BTW.
