Best way to document Array options in PHPDoc?

Question

I\'m struggling to write readable and easy to understand documentation that describes the multi-tree structure for Array options that are passed to a function.

Answer 1

I kinda like this better:

 * @param array $doc
 *          'type'=>Doc::MY_DOC_TYPE,
 *          'created'=>$now,
 *          'modified'=>$now

I just paste in the code from where it gets initialized, quick and easy.
