/// <summary>
/// Tests whether there are any global parameters present in the given document

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))
