In the original implementation, multiple roles cannot be applied to role argument for functions such as desc$add_author(). This is because check_author_args() function called from add_author() calls is_string_or_null() for role argument. This checks whether the role is NULL or character vector with length of 1.
In the develop implementation for that I am creating pull request, role argument can be character vector with any length. Instead of is_string_or_null(), is_character_or_null() is implemented and used.
The following code is allowed in this implementation.
