itemListElement ListItem    or
Text    or
For itemListElement values, you can use simple strings (e.g. "Peter", "Paul", "Mary"), existing entities, or use ListItem.<br/><br/> Text values are best if the elements in the list are plain strings. Existing entities are best for a simple, unordered list of existing things in your data. ListItem is used with ordered lists when you want to provide additional context about the element in that list or when the same item might be in different places in different lists.<br/><br/> Note: The order of elements in your mark-up is not sufficient for indicating the order or elements. Use ListItem with a 'position' property in such cases.
itemListOrder ItemListOrderType    or
Type of ordering (e.g. Ascending, Descending, Unordered).
numberOfItems Integer  The number of items in an ItemList. Note that some descriptions might not fully describe all items in a list (e.g., multi-page pagination); in such cases, the numberOfItems would be for the entire list.

Properties from Thing
additionalProperty PropertyValue  A property-value pair representing an additional characteristics of the entitity, e.g. a product feature or another characteristic for which there is no matching property in<br/><br/> Note: Publishers should be aware that applications designed to use specific properties (e.g.,,, ...) will typically expect such data to be provided using those properties, rather than using the generic property/value mechanism.
additionalType URL  An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. tools may have only weaker understanding of extra types, in particular those defined externally.
