So if you only have 3 entries in the NamespaceArray then the largest index is 2. Depending on usecase, a server can load additional nodesets into its address space. Index 0 is always the base nodeset, and index 1 is for any instances of nodes which do not belong to a specific nodeset. The Attributes NodeId and BrowseName are identifiers.
