* - it binds to the child shellfolder [subpidl1]

*
* Is possible the pidl is a simple pidl. In this case it asks the
* subfolder for the displayname of an empty pidl. The subfolder
* returns the own displayname eg. "::{guid}". This is used for
* virtual folders with the registry key WantsFORPARSING set.
