+          An exception is considered to have escaped (or left) the scope of a span,

+          This may be actually "in flight" in some languages (e.g. if the exception

+### Attributes
+
+
+#### Attribute `exception.escaped`
+
+SHOULD be set to true if the exception event is recorded at a point where it is known that the exception is escaping the scope of the span.
+
+
+An exception is considered to have escaped (or left) the scope of a span,
+if that span is ended while the exception is still logically "in flight".
+This may be actually "in flight" in some languages (e.g. if the exception
+is passed to a Context manager's `__exit__` method in Python) but will
+usually be caught at the point of recording the exception in most languages.
+
+It is usually not possible to determine at the point where an exception is thrown
+whether it will escape the scope of a span.
+However, it is trivial to know that an exception
+will escape, if one checks for an active exception just before ending the span,
+as done in the [example for recording span exceptions](https://opentelemetry.io/docs/specs/semconv/exceptions/exceptions-spans/#recording-an-exception).
+
+It follows that an exception may still escape the scope of the span
+even if the `exception.escaped` attribute was not set or set to false,
+since the event might have been recorded at a time where it was not
+clear whether the exception will escape.
