Use it like this:
- [ #has/_additional_property :: PropertyValue ] or
- [ has_additional_property :: PropertyValue ]
A property-value pair representing an additional characteristic of the entity, e.g. a product feature or another characteristic for which there is no matching property in schema.org.<br/><br/>
Note: Publishers should be aware that applications designed to use specific schema.org properties (e.g. width, color, gtin13, …) will typically expect such data to be provided using those properties, rather than using the generic property/value mechanism.
