    Containerisation enables a tracking of version, author and origin
    for loaded assets.

    Arguments:
        name (str): Name of resulting assembly
        namespace (str): Namespace under which to host container
        nodes (list): Long names of nodes to containerise
        context (dict): Asset information
        loader (str, optional): Name of loader used to produce this container.
        suffix (str, optional): Suffix of container, defaults to `_CON`.

    Returns:
