How to add custom tags in yuidoc

I need to add some custom plugins like @date and @author to the javascript project I'm working on.

We use yuidoc for documentation purposes.

But there are two cases:

1> The @data icon is missing in yuidoc

2> The @author tag exists, but does not appear in documents

This is a list of available tags.

How do I show these tags in my documentation?

Is there a way to add custom tags to display in yuidoc?
