            Lay out multiple GroupBoxes, with one ComboBox inside each. The number of GroupBoxes is determined by the number of features returned by
            binding property: PrintSchemaHelperSource.Features.
            
            Each GroupBox Header displays the print schema feature's display name, bound to PrintSchemaFeatureHelper.DisplayName.
            Each ComboBox's ItemSource property is bound to the list of valid options for that feature i.e. bound to PrintSchemaFeatureHelper.Options.
                Additionally, the ComboBox is bound two-way to to PrintSchemaFeatureHelper.SelectedOption. Therefore, in addition to displaying the option
                selected in the current print ticket, when the selected option is changed via UI selection, 
                a 'set' property is invoked on PrintSchemaFeatureHelper.SelectedOption.

            Each item in the ComboBox has the following structure:
                It's displays the option name via a TextBlock, bound to the IPrintSchemaOption.DisplayName.
                It's 'ForeGround' font color changes based on the IPrintSchemaOption.Constrained property.

            *Note*: Since this is an expensive operation to perfom, the data is retrieved asynchronously (IsAsync=true, below).
