# Opaque types are in general defined as simple byte strings. For the base opaque types there is a corresponding node id definition
# in the nodeset. E.g. Opc.Ua.Types.bsd contains the simple definition for OpaqueType LocaleId. In Opc.Ua.NodeSet2.xml the LocaleId
# is defined as a Subtype of String(i=12) thus LocaleId is a String object.
# TODO we can automate this mapping by loading the NodeSet2.xml and read those mappings automatically. For now we just use this map
