Question about legal characters in Nodeset file|OPC UA Companion Standards|Forum|OPC Foundation

I got a tips from I'm assuming Randy Armstrong here: https://github.com/OPCF-Member...../issues/12 that enums with names that includes a dash '-' is not valid, and it needs to be proper SymbolicNames.

I'm assuming this would be invalid:

<UADataType NodeId="ns=1;i=71" BrowseName="1:CtlModelKind">
<DisplayName>CtlModelKind</DisplayName>
<References>
<Reference ReferenceType="HasProperty">ns=1;i=72</Reference>
<Reference ReferenceType="HasSubtype" IsForward="false">i=29</Reference>
</References>
<Definition Name="1:CtlModelKind">
<Field Name="status-only" Value="0" />
<Field Name="direct-with-normal-security" Value="1" />
<Field Name="sbo-with-normal-security" Value="2" />
<Field Name="direct-with-enhanced-security" Value="3" />
<Field Name="sbo-with-enhanced-security" Value="4" />
</Definition>
</UADataType>

I see some related changes done to the NodeSet files here: IEC61850/Opc.Ua.IEC61850-6.NodeSet2.xml

I cannot find this requirement in the NodeSet XML schema file: https://files.opcfoundation.or.....odeSet.xsd

To me it looks like the Name attribute can be a type="xs:string", and the changes done to the Name attribute in the IEC61850 NodeSet file is not needed.

Is there something I'm missing here?
