There are must be array types, multiple types and object types syntax description.

Like started in http://css.dzone.com/articles/introduction-jsdoc:

Type annotations: You can document the type of a value by putting the type name in braces after the appropriate tags. Variations:

Single type: @param {string} name Multiple types: @param {string|number} idCode Arrays of a type: @param {string[]} names

But how describe list of fields for declaring variable?
