/// </summary>
/// <param name="document">Revit project document.</param>
/// <returns>A set of ElementIds of global parameter elements</returns>
public bool ContainsGlobalParameters(Document document)
{
    // Global parameters are not available in all documents.
    // They are available in projects, but not in families.
    if (GlobalParametersManager.AreGlobalParametersAllowed(document))
