# identifier

A string that uniquely identifies a context among its siblings.

## Declaration

```swift
var identifier: String { get }
```

## Discussion

Discussion All contexts with a given parent context must have different identifiers. No such requirement exists for contexts that have different parent contexts. So, for example, the chapter-1 and chapter-2 contexts can each have child contexts with the identifier section-1, but chapter-1 can’t have two contexts with that identifier.
