Description

When using an XPath2 filter, and you don't add:
domSignContext.putNamespacePrefix(Transform.XPATH2, "xpath2");
the marshalling completely fails as XPath receives a ds: prefix, instead of a prefix pointing to
http://www.w3.org/2002/06/xmldsig-filter2

This should not happen.

Example code:
DOMSignContext domSignContext = new DOMSignContext(privateKey, parentElement);
domSignContext.setDefaultNamespacePrefix("ds");
// next is required for correct marshalling
domSignContext.putNamespacePrefix(Transform.XPATH2, "xpath2");

XMLSignatureFactory xmlSignatureFactory = XMLSignatureFactory
.getInstance("DOM", new XMLDSigRI());

List<Reference> references = new LinkedList<Reference>();
List<Transform> transforms = new LinkedList<Transform>();
List<XPathType> types = new LinkedList<XPathType>();
Map<String, String> xpathNamespaceMap = new HashMap<String, String>();
xpathNamespaceMap.put("ds", "http://www.w3.org/2000/09/xmldsig#");
types.add(new XPathType("/descendant::*[name()='ds:Signature']",
XPathType.Filter.SUBTRACT, xpathNamespaceMap));
Transform envelopedTransform = xmlSignatureFactory.newTransform(
CanonicalizationMethod.XPATH2, new XPathFilter2ParameterSpec(
types));
transforms.add(envelopedTransform);
transforms.add(xmlSignatureFactory.newTransform(
CanonicalizationMethod.EXCLUSIVE,
(C14NMethodParameterSpec) null));
Reference reference = xmlSignatureFactory.newReference("",
xmlSignatureFactory.newDigestMethod(DigestMethod.SHA256, null),
transforms, null, null);
references.add(reference);
