Hi Marcos, The position of the <object> element in the example provided in http://www.w3.org/TR/widgets-digsig/ section 1.4 is not correct in that the <object> occurs before the <SignatureValue>.
The DTD provided fo the XMLDIG11 http://www.w3.org/TR/2009/WD-xmldsig-core1-20090226/xmldsig-core-schema. dtd and also the example http://www.w3.org/TR/2009/WD-xmldsig-core1-20090226/signature-example.xm l instruct us that it should occur AFTER the <SignatureValue>. The major problem with the example is that even it is non-normative it may be used by implementors as a template, and some existing XML security tools chains (i.e. Apache XML security library) will fail to process a template that has the <object> in the wrong order. Kind regards, Christian
