`xl.meta` carries three types of object entries which designate the type of version object stored.

- ObjectType (default)
- LegacyObjectType (preserves existing deployments and older xl.json format)
- DeleteMarker (a versionId to capture the DELETE sequences implemented primarily for AWS spec compatibility)

type Token struct {
	ScanToken
	text string
