Dunno. Most will have such a feature, but the implementation can vary.

The clipboard should not be affected by DnD at all. It's only the 
mechanism, how data formats are managed by the clipboard, that suggests 
to use the same model to describe and handle DnD data as well.

DnD uses data containers, which may be accessed like the clipboard (same 
API).
