>
> Currently the createMarshaller and createUnmarshaller methods parse the
> javax.xml.validation.Schema from scratch, which is a severe overhead
> considering that a Schema instance is threadsafe and it is encuraged to
> re-use it as much as possible
> (see
> http://xerces.apache.org/xerces2-j/javadocs/api/javax/xml/validation/Schema.html)
>
> I extended the DataFormat and cached the parsed Schema and did a small
> benchmark that parsed an input document 64000 times:
> JaxbDataFormat: 3:18
> AltJaxbDataFormat: 0:35
