025/**
026 * A pairing of a {@link RdfXmlAbbrevSerializer} and {@link RdfXmlParser} into a single class with convenience to/of methods.
027 *
028 * <p>
029 *    The general idea is to combine a single serializer and parser inside a simplified API for serializing and parsing POJOs.
030 *
031 * <h5 class='figure'>Examples:</h5>
032 * <p class='bjava'>
033 *    <jc>// Using instance.</jc>
034 *    RdfXmlAbbrev <jv>rdfXmlAbbrev</jv> = <jk>new</jk> RdfXmlAbbrev();
035 *    MyPojo <jv>myPojo</jv> = <jv>rdfXmlAbbrev</jv>.read(<jv>string</jv>, MyPojo.<jk>class</jk>);
036 *    String <jv>string</jv> = <jv>rdfXmlAbbrev</jv>.write(<jv>myPojo</jv>);
037 * </p>
038 * <p class='bjava'>
039 * <jc>// Using DEFAULT instance.</jc>
040 *    MyPojo <jv>myPojo</jv> = RdfXmlAbbrev.<jsf>DEFAULT</jsf>.read(<jv>string</jv>, MyPojo.<jk>class</jk>);
041 *    String <jv>string</jv> = RdfXmlAbbrev.<jsf>DEFAULT</jsf>.write(<jv>myPojo</jv>);
