Difficulties to add tag SignaturePolicyIdentifier

Hi,

Firstly, all my best wishes to all of you :)

 I have difficulties to add this tags :
<xad:SignaturePolicyIdentifier>
    <xad:SignaturePolicyId>
        <xad:SigPolicyId><xad:Identifier>urn:oid:1.2.250.1.131.1.5.18.21.1.4</xad:Identifier>
<xad:Description>Politique de signature Helios de la DGFiP</xad:Description>
        </xad:SigPolicyId>
        <xad:SigPolicyHash>
            <xad:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/>
            <xad:DigestValue>Jkdb+aba0Hz6+ZPKmKNhPByzQ+Q=</xad:DigestValue>
        </xad:SigPolicyHash>
        <xad:SigPolicyQualifiers>
            <xad:SigPolicyQualifier>
                <xad:SPURI>https://portail.dgfip.finances.gouv.fr/documents/PS_Helios_DGFiP.pdf</xad:SPURI>
            </xad:SigPolicyQualifier>
        </xad:SigPolicyQualifiers>
    </xad:SignaturePolicyId>
</xad:SignaturePolicyIdentifier>

I can get this :
<xades:SignaturePolicyIdentifier>
    <xades:SignaturePolicyId>
        <xades:SigPolicyId>
            <xades:Identifier>urn:oid:1.2.563</xades:Identifier>
        </xades:SigPolicyId>
        <xades:SigPolicyHash>
            <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/>
            <ds:DigestValue>Jkdb+aba0Hz6+ZPKmKNhPByzQ+Q=</ds:DigestValue>
        </xades:SigPolicyHash>
    </xades:SignaturePolicyId>
</xades:SignaturePolicyIdentifier>

I'm using this code:
XadesSigningProfile p = new XadesTSigningProfile(kp)
                 .withPolicyProvider(new SignaturePolicyInfoProvider() {
                    @Override
                    public SignaturePolicyBase getSignaturePolicy() {
                         try {
                             return new SignaturePolicyIdentifierProperty(new ObjectIdentifier("urn:oid:1.2.563"),
                                     new URL("https://portail.dgfip.finances.gouv.fr/documents/PS_Helios_DGFiP.pdf").openStream());
                         } catch (MalformedURLException ex) {
                             Logger.getLogger(StelaSign.class.getName()).log(Level.SEVERE, null, ex);
                             return new SignaturePolicyImpliedProperty();
                         } catch (IOException ex) {
                             Logger.getLogger(StelaSign.class.getName()).log(Level.SEVERE, null, ex);
                             return new SignaturePolicyImpliedProperty();
                         }
                    }
                 })               
                  .withAlgorithmsProviderEx(new AlgorithmsProviderEx() {
                    @Override
                    public Algorithm getSignatureAlgorithm(String string) throws UnsupportedAlgorithmException {
                       return new GenericAlgorithm(XMLSignature.ALGO_ID_SIGNATURE_RSA_SHA1);
                    }
                    @Override
                    public Algorithm getCanonicalizationAlgorithmForSignature() {
                        //return new GenericAlgorithm(Canonicalizer.ALGO_ID_C14N_WITH_COMMENTS);
                        return new GenericAlgorithm(Canonicalizer.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
                    }
                    @Override
                    public Algorithm getCanonicalizationAlgorithmForTimeStampProperties() {
                        //return new GenericAlgorithm(Canonicalizer.ALGO_ID_C14N11_WITH_COMMENTS);
                        return new GenericAlgorithm(Canonicalizer.ALGO_ID_C14N_EXCL_OMIT_COMMENTS);
                    }
                    @Override
                    public String getDigestAlgorithmForDataObjsReferences() {
                        //return DigestMethod.SHA1;                       
                        return Constants.ALGO_ID_DIGEST_SHA1;
                    }
                    @Override
                    public String getDigestAlgorithmForReferenceProperties() {
                         return Constants.ALGO_ID_DIGEST_SHA1;
                    }
                    @Override
                    public String getDigestAlgorithmForTimeStampProperties() {
                        return Constants.ALGO_ID_DIGEST_SHA1;
                    }
                })              
                ;

I can't integrate tags SigPolicyQualifiers and description for the tag 
SigPolicyId.

Does anyone knows the solution?

By advance, thank you !
Regards.
