AllSignedDataObjects - undefined ?

[asukisun]

Thank you for developing such a useful library.
Regarding the output part of "AllSignedDataObjects", I would like you to check if there are any problems with the logic.

I am trying to generate the following output using XML signatures with xadesjs.

<xades:SignedDataObjectProperties>
    <xades:CommitmentTypeIndication>
        <xades:CommitmentTypeId>
            <xades:Identifier Qualifier="OIDAsURN">urn:oid:1.2.840.113549.1.9.16.6.1</xades:Identifier>
        </xades:CommitmentTypeId>
        <xades:AllSignedDataObjects/>
    </xades:CommitmentTypeIndication>
</xades:SignedDataObjectProperties>

#Here is the relevant code snippet:

const commitmentTypeIndication = new xadesjs.xml.CommitmentTypeIndication();

commitmentTypeIndication.CommitmentTypeId.Identifier.Qualifier = "OIDAsURN";
commitmentTypeIndication.CommitmentTypeId.Identifier.Value = ["urn:oid:1.2.840.113549.1.9.16.6.1"];

commitmentTypeIndication.AllSignedDataObjects = true;
commitmentTypeIndication.MimeType = "text/xml";

signedXml.SignedProperties.SignedDataObjectProperties.DataObjectFormats.Add(commitmentTypeIndication);

// (omission)
signedDocument = signedXml.Sign(  (omission) );

When I put some value into commitmentTypeIndication.AllSignedDataObjects
I get <xades:AllSignedDataObjects>undefined</xades:AllSignedDataObjects>
in the output.

However, it always appears as
<xades:AllSignedDataObjects>undefined</xades:AllSignedDataObjects>

No matter what value I enter, "undefined" is output.

Is this "undefined" behavior intentional?

#Actual_Output

<xades:SignedDataObjectProperties>
    <xades:CommitmentTypeIndication>
        <xades:CommitmentTypeId>
            <xades:Identifier Qualifier="OIDAsURN">urn:oid:1.2.840.113549.1.9.16.6.1</xades:Identifier>
        </xades:CommitmentTypeId>
        <xades:AllSignedDataObjects>undefined</xades:AllSignedDataObjects>
    </xades:CommitmentTypeIndication>
</xades:SignedDataObjectProperties>

Two points to add:

1,
Changing to commitmentTypeIndication.AllSignedDataObjects = ""; also yields the same result.

2,
If the line commitmentTypeIndication.AllSignedDataObjects = true;
is commented out, the AllSignedDataObjects element disappears from the signature.
