/**
 * A helper class to transform to and from {@link org.springframework.xml.transform.StringSource} implementations
 * available in both Camel and Spring Webservices.
 * <p/>
 * Rationale: most of the time this converter will not be used since both Camel
 * and Spring-WS use the {@Source} interface abstraction. There is
 * however a chance that you may end up with incompatible {@link org.springframework.xml.transform.StringSource}
 * implementations, this converter handles these (corner)cases.
 * <p/>
 * Note that conversion options are limited by Spring's {@link org.springframework.xml.transform.StringSource}
 * since it's the most simple one. It has just one constructor that accepts a
 * String as input.
