> xmp.addXMLNSMapping(XMPSchemaPDFAId.NAMESPACE, XMPSchemaPDFAId.class);

> xmp.getSchemaByClass(XMPSchemaPDFAId.class);
> System.out.println(schema.getConformance() + " " + schema.getPart());
> {code}
> This fails with an NPE because
> {{xmp.getSchemaByClass(XMPSchemaPDFAId.class)}} is null.
> While most PDFBox users use xmpbox, some may still use jempbox due to bugs,
> especially our sister project Apache Tika.
