* For most attributes this is true.
* The data stored in the attribute is equal to the data stored in the field value in the document.
*
* For predicate and reference attributes this is false.
* The original data is transformed (lossy) before it is stored in the attribute.
* During update we also need to update the field value in the document.
*
* For struct field attributes this is false.
* A struct field attribute typically represents a sub-field of a more complex field (e.g. map of struct or array of struct).
* During update the complex field is first updated in the document,
* then the struct field attribute is updated based on the new content of the complex field.
