The hierarchy of a heading in relation other headings.
Assistive technologies can use this to improve a users navigation
through multiple headings. When users navigate through top level
headings they expect the content for each heading to be unrelated.
Creates a new instance with the specified raw value.
If there is no value of the type that corresponds with the specified raw
value, this initializer returns `nil`. For example:
enum PaperSize: String {
case A4, A5, Letter, Legal
}
print(PaperSize(rawValue: "Legal"))
// Prints "Optional(PaperSize.Legal)"
print(PaperSize(rawValue: "Tabloid"))
// Prints "nil"
- Parameter rawValue: The raw value to use for the new instance.

var rawValue: Int { get }
The corresponding value of the raw type.
A new instance initialized with `rawValue` will be equivalent to this
instance. For example:
enum PaperSize: String {
case A4, A5, Letter, Legal
}
let selectedSize = PaperSize.Letter
print(selectedSize.rawValue)
// Prints "Letter"
print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!)
// Prints "true"
