Usually, this component will simply contain labelled Apache Trinidad input
components in its main content - these are inputText, inputFile, inputColor, inputListOfValues,
inputDate, selectBooleanCheckbox, selectBooleanRadio, selectOneChoice, selectOneListbox, selectOneRadio,
selectManyCheckbox, and selectManyListbox. These components must have their "simple" attribute set to
false, which is the default, and will cause the labels and fields inside the panelFormLayout to be aligned
vertically.
