    ///
    /// The [`Notebook`][crate::Notebook] implementation of the [`Buildable`][crate::Buildable] interface
    /// supports placing children into tabs by specifying “tab” as the
    /// “type” attribute of a `<child>` element. Note that the content
    /// of the tab must be created before the tab can be filled.
    /// A tab child can be specified without specifying a `<child>`
    /// type attribute.
    ///
    /// To add a child widget in the notebooks action area, specify
    /// "action-start" or “action-end” as the “type” attribute of the
    /// `<child>` element.
    ///
    /// An example of a UI definition fragment with [`Notebook`][crate::Notebook]:
