     * This list is based on the data type of the property rather than how the content is rendered.
     * In order to support markdown, a property needs to support the `MarkdownRef` data type,
     * which is included in `Text`, defined in `FormDefinition`. If a Form Element subsequently
     * passed this to `renderText()`, it would still handle the markdown appropriately. Styling would be stripped out
     * and you would be left with readable text. For example "**hello** there" would become "hello there".
     *
     * On the other hand, properties that expect a `string` must not ever be set to a `MarkdownRef`
     * as the element is not expected to perform any conversion on them.
     * @param propertyName The name of the property to check
     * @returns True if this property could accept markdown, false otherwise.
