Hi there. I was thinking of building two custom macro parameters, but I need to transfer IPublished content and IEnumerable(string) as parameters. Is there somewhere I can see which types are allowed as parameters?

I found this snippet, is says a valueType of "STRING" is allowed. But are there more?

{
 "propertyEditors": [ 
 {
    "alias": "tooorangey.ImagePosition",
    "name": "Image Position",
    "isParameterEditor": true,
    "editor": {
        "view": "~/App_Plugins/tooorangey.ImagePosition/ImagePosition.html",
        "valueType": "STRING"
    }
}],
 "javascript": [
    "~/App_Plugins/tooorangey.ImagePosition/ImagePosition.controller.js"
 ]
}
