    NOTE FOR AZURE AUTOMATION DSC CLIENTS:

    Partial Configs are NOT supported yet. Same should be true for Composite resources,
    but actually isn't - they work as expected, due to this:

    "(...) However, DSC composite resources can be imported and used in Azure Automation DSC Configurations like in local PowerShell, enabling configuration reuse."

    SOURCE: https://docs.microsoft.com/en-us/azure/automation/automation-dsc-overview

    Anyway, I've added the functionality (partial configs) for future use

    Cheers,
    Rad
