The nsid (namespace identifier) type creates a context in which namespace identifiers can be bound.
| # fncreate -t nsid org/sales/site/alameda.bldg-5/ | 
creates the nsid context for the site alameda.bldg-5 and permits the creation of subcontexts such as service/. Continuing with this example, you could then execute the command
| # fncreate -t service org/sales/site/alameda.bldg-5/service/ | 
to create the service context for alameda.bldg-5.
The nsid context created is owned by the administrator who ran the fncreate command.
