Presence of the Element in the Stream

(defunct)
The element has been marked for removal from the workspace or stream with the Defunct command. The element will be removed from the stream (in the depot) when you promote the element to the parent stream.
(xlinked)
This version of the element appears in the stream by virtue of a cross-link, either on the element itself or on its parent directory or a higher-level directory. (Cross-linking a directory also cross-links the entire subtree below it.)
(twin)
The element is one of multiple elements in the workspace that exist at the same pathname. At most one of these elements can be accessed through the pathname. The others can be accessed through their unique element IDs.
