Add passThroughAttribute to SelectItem

If I want to add passThroughAttributes to some of the options of a select-element I can use f: passThroughAttribute as child-component of f:selectItem.

But normally I'm using a List of SelectItems to generate the options. In contrast to UiComponent SelectItem does not have a method getPassThroughAttributes.

Anybody knows a reason why?

It's because it doesn't have a Renderer associated. In case of <f:xxx> components (taghandlers and models) it's instead the closest parent <h:xxx> component (UIComponent instances) or, if any, the closest nested <h:xxx> component which does have a Renderer associated. The Renderer is namely the one responsible for generating all HTML output, including passthrough attributes. Note that the passthrough attributes have in such case to be set on the <h:xxx> component itself.

If you intend to control/manipulate the attributes of generated <option> elements, then you can't go around creating a custom Renderer, if necessary based on the standard Renderer implementation.
