I'm trying to sign an xml but this is showing an Id attribute in the Signature tag and the xmlns attribute is not appearing.

This is the xml generated:

<Signature Id="Id-80170FF0-0678-47D5-8C8B-771AA4E334E6">
            <SignedInfo>
                <CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/>
                <SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/>
                <Reference URI="#ID2102103519037442275900010755000000003309115569507501">
