    /// The GtkLabel implementation of the GtkBuildable interface supports a
    /// custom `<attributes>` element, which supports any number of `<attribute>`
    /// elements. The `<attribute>` element has attributes named “name“, “value“,

    /// ```
    ///
    /// To create a mnemonic for a widget alongside the label, such as a
    /// [`Entry`][crate::Entry], you have to point the label at the entry with
    /// [`LabelExt::set_mnemonic_widget()`][crate::prelude::LabelExt::set_mnemonic_widget()]:

    /// **⚠️ The following code is in C ⚠️**

    /// # Markup (styled text)
    ///
    /// To make it easy to format text in a label (changing colors,
    /// fonts, etc.), label text can be provided in a simple
    /// [markup format][PangoMarkupFormat].
    ///
    /// Here’s how to create a label with a small font:
    ///
    ///
    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
    ///   GtkWidget *label = gtk_label_new (NULL);
    ///   gtk_label_set_markup (GTK_LABEL (label), "<small>Small text</small>");
    /// ```
    ///
    /// (See [complete documentation][PangoMarkupFormat] of available
    /// tags in the Pango manual.)
    ///
    /// The markup passed to [`LabelExt::set_markup()`][crate::prelude::LabelExt::set_markup()] must be valid; for example,
    /// literal <, > and & characters must be escaped as &lt;, &gt;, and &amp;.
    /// If you pass text obtained from the user, file, or a network to
    /// [`LabelExt::set_markup()`][crate::prelude::LabelExt::set_markup()], you’ll want to escape it with
    /// `g_markup_escape_text()` or `g_markup_printf_escaped()`.
    ///
    /// Markup strings are just a convenient way to set the [`pango::AttrList`][crate::pango::AttrList] on
    /// a label; [`LabelExt::set_attributes()`][crate::prelude::LabelExt::set_attributes()] may be a simpler way to set
    /// attributes in some cases. Be careful though; [`pango::AttrList`][crate::pango::AttrList] tends to
    /// cause internationalization problems, unless you’re applying attributes
    /// to the entire string (i.e. unless you set the range of each attribute
    /// to [0, `G_MAXINT`)). The reason is that specifying the start_index and
    /// end_index for a `PangoAttribute` requires knowledge of the exact string
    /// being displayed, so translations will cause problems.
    ///
    /// # Selectable labels
    ///
    /// Labels can be made selectable with [`LabelExt::set_selectable()`][crate::prelude::LabelExt::set_selectable()].
    /// Selectable labels allow the user to copy the label contents to
    /// the clipboard. Only labels that contain useful-to-copy information
    /// — such as error messages — should be made selectable.
    ///
    /// # Text layout # {`label`-text-layout}
    ///
    /// A label can contain any number of paragraphs, but will have
    /// performance problems if it contains more than a small number.
    /// Paragraphs are separated by newlines or other paragraph separators
    /// understood by Pango.
    ///
    /// Labels can automatically wrap text if you call
    /// [`LabelExt::set_line_wrap()`][crate::prelude::LabelExt::set_line_wrap()].
    ///
    /// [`LabelExt::set_justify()`][crate::prelude::LabelExt::set_justify()] sets how the lines in a label align
    /// with one another. If you want to set how the label as a whole
    /// aligns in its available space, see the `property::Widget::halign` and
    /// `property::Widget::valign` properties.
    ///
    /// The `property::Label::width-chars` and `property::Label::max-width-chars` properties
    /// can be used to control the size allocation of ellipsized or wrapped
    /// labels. For ellipsizing labels, if either is specified (and less
    /// than the actual text size), it is used as the minimum width, and the actual
    /// text size is used as the natural width of the label. For wrapping labels,
    /// width-chars is used as the minimum width, if specified, and max-width-chars
    /// is used as the natural width. Even if max-width-chars specified, wrapping
    /// labels will be rewrapped to use all of the available width.
    ///
    /// Note that the interpretation of `property::Label::width-chars` and
    /// `property::Label::max-width-chars` has changed a bit with the introduction of
    /// [width-for-height geometry management.][geometry-management]
    ///
    /// # Links
    ///
    /// Since 2.18, GTK+ supports markup for clickable hyperlinks in addition
    /// to regular Pango markup. The markup for links is borrowed from HTML,
    /// using the ``<a>`` with “href“ and “title“ attributes. GTK+ renders links
    /// similar to the way they appear in web browsers, with colored, underlined
    /// text. The “title“ attribute is displayed as a tooltip on the link.
    ///
    /// An example looks like this:
    ///
    ///
    ///
    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
    /// const gchar *text =
    /// "Go to the"
    /// "<a href=\"http://www.gtk.org title=\"&lt;i&gt;Our&lt;/i&gt; website\">"
    /// "GTK+ website</a> for more...";
    /// GtkWidget *label = gtk_label_new (NULL);
    /// gtk_label_set_markup (GTK_LABEL (label), text);
    /// ```
    ///
    /// It is possible to implement custom handling for links and their tooltips with
    /// the `signal::Label::activate-link` signal and the [`LabelExt::current_uri()`][crate::prelude::LabelExt::current_uri()] function.
