The example shows that you can sign several elements and that for each element a signature is created as sibling. The elements to be signed must have an attribute of type ID. The ID type of the attribute must be defined in the XML schema (see option schemaResourceUri). You specify a list of XPATH expressions pointing to attributes of type ID (see option xpathsToIdAttributes). These attributes determine the elements to be signed. The elements are signed by the same key given by the keyAccessor bean. Ements with higher (=deeper) hierarachy level are signed first. In the example, the element "C" is signed before the element "A".

Java DSL example

from("direct:detached")
  .to("xmlsecurity:sign://detached?keyAccessor=#keyAccessorDefault&xpathsToIdAttributes=#xpathsToIdAttributes&schemaResourceUri=Test.xsd")
  .to("xmlsecurity:verify://detached?keySelector=#keySelectorDefault&schemaResourceUri=org/apache/camel/component/xmlsecurity/Test.xsd")
  .to("mock:result");
