just a question about virDomainLookupByName function

[Philippe Berthault <Philippe.Berthault@xxxxxxxx>]

An ID may be passed to virDomainLookupByName function.
In exemple:
   virDomainLookupByName(conn, "1")
   is equivalent to
   virDomainLookupByID(conn, 1)

This functionality is very useful but isn't written in the libvirt 
documentation.

Is this functionality will continue to exist in future versions of 
libvirt or not ?

Thanks,
Philippe Berthault.
