  1. description : Allows for the description to be an array of nodes (e.g. an array of inline content, or a couple of paragraphs), or a string. The minItems restriction avoids a string being coerced into an array with a single string item.
  2. identifiers : Some identifiers have specific properties e.g the issn property for the Periodical type. These should be used in preference to this property which is intended for identifiers that do not yet have a specific property. Identifiers can be represented as strings, but using a PropertyValue will usually be better because it allows for propertyID (i.e. the type of identifier).
