Hello, I'm using UA-ModelCompiler and I had problems with the Locale and possible translations.

In my ModelDesign.xml file I want to insert the possibility of having a description with multiple language options.
If I write this code

<opc:Object SymbolicName="Object1" TypeDefinition="MyType" SupportsEvents="true">
    <opc:BrowseName>Object1</opc:BrowseName>
    <opc:Description Locale ="en-US">This is the first object</opc:Description>
    <opc:Description Locale ="it-IT">Questo è il primo oggetto</opc:Description>
</opc:Object>

I get some kind of error:

However, running the UA.ModelCompiler.exe does not generate any errors.

Running my server I can see only the first Description even if In the beginning of the file I have:

<opc:ModelDesign
[...]
DefaultLanguage="it-IT">

The Reference (https://reference.opcfoundation.org/v104/Core/docs/Part6/F.10/) says

<Value>
    <ListOfExtensionObject xmlns="http://opcfoundation.org/UA/2008/02/Types.xsd">
        <ExtensionObject>
            <TypeId>
                <Identifier>i=297</Identifier>
            </TypeId>
            <Body>
                <Argument>
                    <Name>ConfigData</Name>
                    <DataType>
                        <Identifier>i=15</Identifier>
                    </DataType>
                    <ValueRank>-1</ValueRank>
                    <ArrayDimensions />
                    <Description>
                        <Text>[English Translation for Description]</Text>
                    </Description>
                </Argument>
            </Body>
        </ExtensionObject>
    </ListOfExtensionObject>
</Value>
<Translation>
    <Field Name="Description">
        <Text Locale="de-DE">[German Translation for Description]</Text>
        <Text Locale="fr-FR">[French Translation for Description]</Text>
    </Field>
</Translation>

so I also tried to follow this pattern but it doesn't recognize Descriprion, Text, Translation ... well, I don't know how to make it work.

Then I saw that the UA Model Design.xsd and it says (about Description on line 202-204):
"The Description the value of the Description attribute for the Node. This element includes an optional key that can be used to look up the Description for other locales in a resource DB. The validator automatically creates a generic Description from the BrowseName and NodeClass." (and the same for DisplayName).

I didn't find any other hint to use the Key of Description and even less how/where create/use the database with the related LocaleText.

Can you please help me figure out how to use multilanguage (in both cases, with Locale and Key)?
Thanks in advance!

Specifying a locale is a missing feature in the ModelDesign schema.
I will investigate what is involved in added it.
