This object type defines the metadata for a namespace provided by the Server.
Instances of this object allow Servers to provide more information like version information in addition to the namespace URI. Important information for aggregating Servers is provided by the StaticNodeIdTypes, StaticNumericNodeIdRange and StaticStringNodeIdPattern properties.
The browse name of instances of this type shall be derived from the represented namespace. This can, for example, be done by using the index of the namespace in the namespace array as namespaceIndex of the UnifiedAutomation.UaBase.QualifiedName and the namespace URI as name of the UnifiedAutomation.UaBase.QualifiedName.

getset |
Defines whether all nodes of the namespace are accessible in the Server or only a subset.
It is set to FALSE if the full namespace is provided and TRUE if not.
Static nodes are identical for all attributes in all Servers, including the Value attribute. For type definition nodes, also the instance declarations shall be identical. That means that for static nodes the semantic is always the same. Namespaces with static nodes are for example namespaces defined by standard bodies like the OPC Foundation. This is important information for aggregating Servers. If the namespace is dynamic and used in several Servers the aggregating Server needs to distinguish the namespace for each aggregated Server. The static nodes of a namespace only need to be handled once, even if it they are used by several aggregated Servers.
