 * Trait QuotesTrait
 *
 * The quotes attribute may set on cs:text. When set to “true” (“false” is default), the rendered text is wrapped in
 * quotes (the quotation marks used are terms). The localized punctuation-in-quote option controls whether an adjoining
 * comma or period appears outside (default) or inside the closing quotation mark.
