And since no properties are defined especially for WebPageElement I don't think we're missing out on much. I also don't see a lot of value in treating a breadcrumb list as a creative work. It's essentially just a data structure with a particular known kind of content. I would love to hear of WPFooter etc being used (e.g. for accessibility).
