Does INSPIRE validator support multiple natural languages TranslationTemplateBundle?

[klimeto]

Dear developers,

Is there a possibility to add another language to a TranslationTemplateBundle, e.g. this one as following example:

<LangTranslationTemplateCollection name="TR.invalidSchema">
			<translationTemplates>
				<TranslationTemplate language="en" name="TR.invalidSchema">XML document '{filename}': The file has {count} schema validation error(s).
                                </TranslationTemplate>
                               <TranslationTemplate language="sk" name="TR.invalidSchema">TRANSLATION TO SK '{filename}': TRANSLATION TO SK {count} TRANSLATION TO SK.
                                </TranslationTemplate>
			</translationTemplates>
</LangTranslationTemplateCollection>

We would like to provide our users error messages in our own language, and therefore we have been looking for the most correct way.

According to the schema translationTemplates element allows many TranslationTemplate which I guess is created in order to support multiple languages.

The questions is does the backend API application support it, and if yes how to configure it which language to be used while returning the validation messages.

Many thanks for help!
