[O] [Exporter] Why is :author a list in the communication channel?

[Thorsten Jolitz]

Hi List, 

I wonder why the :author attribute in INFO is a list (while :email,
:creator and others are not)?

It would make sense if several authors would be collected as a list of
strings, like e.g.

,-------------------------------------
| ("Thorsten Jolitz" "Thomas Mueller")
`-------------------------------------

but I don't know how to write the #+AUTHOR: information to achieve
that.

This

,----------------------------------------
| #+AUTHOR: Thorsten Jolitz Thomas Mueller
`----------------------------------------

and other versions I tried (with comma or double quotes as separators)
always results in a single string element inside the :author list

,-----------------------------------
| ("Thorsten Jolitz Thomas Mueller")
`-----------------------------------

so why make the value a list and not a string?
