The following information in an OPC UA NodeSet is lost when converting to OPC UA FX AML:

• NamespaceIndexes: OPC UA FX AML does not use NamespaceIndexes. It always uses the NamespaceURI as a string;
• Bit order in OptionSets and Bitmasks: In OPC UA FX AML, OptionSet and bit masks are defined with an unordered list of boolean AML attributes;
• builtinType values are defined as string and not as integer;
• AttributeId values are defined as string and not as integer.

When creating a NodeSet from an OPC UA FX AML file, the missing information needs to be taken from the NodeSet files that define the types used in the OPC UA FX AML file.
