| Description |
Gets the namespace of the identifier. The namespace
reflects the domain in which the identifier is unique.
When using a global identifier schema, the namespace may
indicate the name of the scheme. When using a local
identification scheme, the namespace may be more specific,
such as the name of a database or file in which the
identifiers exist. Federating adapters may use a custom
namespace to include information for routing. This method
is used to compare one Id to another.
