public @interface XmlTransformation
    Transformation is an optional annotation for org.eclipse.persistence.mappings.oxm.XMLTransformationMapping. TransformationMapping allows to map an attribute to one or more database columns. Transformation annotation is an optional part of TransformationMapping definition. Unless the TransformationMapping is write-only, it should have a ReadTransformer, it defines transformation of xml data value(s)into attribute value. Also unless it's a read-only mapping, either WriteTransformer annotation or WriteTransformers annotation should be specified. Each WriteTransformer defines transformation of the attribute value to a single xml field value (XPath is specified in the WriteTransformer).
