2. RequestTransformedDocument.
DSS Core 1.0.
This element does not seem to work in the case that the request contains more than one XML (XAdES) signatures. It only contains one attribute for identifying the number of a ds:Reference. And the text only speaks about "the" XML signature. If the text is changed to make it clear that the integer i value in the attribute corresponds to that ds:Reference that occupies the ith position once the request has been serialized, then this could work.
