class MyCustomLayout extends iam.api.types.CustomLayout {

    // Additional HTML rendering that cannot be done using header/footer/content. 
    // Note that this method can be used in combination with methods headerHtml, footerHtml and contentHtml. 
    // Caution: this method can be invoked more than once on a page: 
    // when entering a page, but also every time when switching the language. 
    // For a correct behavior, it must therefore be ensured that previous renderings are undone.
