The list of data types displayed on the Structured Data Markup Helper is limited in comparison to what is available on Schema.org
I am wondering if Google supports rich snippets for all schema.org data types as is possibly suggested by https://support.google.com/webmasters/answer/146645
collaboration by Google, Microsoft, and Yahoo! to improve the web by creating a structured data markup schema supported by major search engines.
schema.org
and include the Expected Type for the Property, and your code validates in the Google Structured Data Testing Tool, you should be fine.
