Change the QualifyingProperties Target

[shunkica]

It appears the library is setting a randomly generated Id to the QualifyingPropertes Target attribute when SignedXml is constructed, and I do not see any way to change this.XmlSignature.Id before this happens.

export class SignedXml extends XmlDSigJs.SignedXml {

    constructor(node?: Document | Element) {
        super(node);

        this.CreateQualifyingProperties();
    }
    
    protected CreateQualifyingProperties() {
        if (this.Properties) {
            throw new XmlCore.XmlError(XmlCore.XE.XML_EXCEPTION, "Cannot create QualifyingProperties cause current signature has got one. You must create CounterSignature");
        }

        const rnd = XmlDSigJs.Application.crypto.getRandomValues(new Uint8Array(6)) as Uint8Array;
        const id = XmlCore.Convert.ToHex(rnd);

        this.XmlSignature.Id ||= `id-${id}`;
        const dataObject = new XAdES.DataObject();
        dataObject.QualifyingProperties.Target = `#${this.XmlSignature.Id}`;
        dataObject.QualifyingProperties.SignedProperties.Id ||= `xades-${this.XmlSignature.Id}`;

        this.properties = dataObject.QualifyingProperties;
        this.XmlSignature.ObjectList.Add(dataObject);
    }
    
}

Shouldn't this Id be the same as the Signature id set in SignedXml().Sign fourth parameter (OptionsXAdES)?

From XAdES spec:

4.2 The QualifyingProperties

The mandatory Target attribute refers to the XML signature with which the qualifying properties are associated.
