# elements

The document elements you’re requesting.

## Declaration

```swift
var elements: [MobileDocumentDisplayRequest.Element]
```

## Discussion

Discussion note: A request isn’t considered valid if the list of elements is empty, contains duplicates, or contains both age and ageAtLeast(_:). If you call requestDocument(_:) with an invalid request, the framework throws an MobileDocumentReaderError.invalidRequest error.
