/** Property wrapper specifying that a given property should be encoded and decoded as an XML element.

 For example, this type
 ```swift
 struct Book: Codable {
     @Element var id: Int
 }
 ```

 will encode value `Book(id: 42)` as `<Book><id>42</id></Book>`. And vice versa,
 it will decode the former into the latter.
