[xmlsec] Duplicated X509Certificate

[Marcos Bontempo]

Hello,
I'm signing a XML file with this command:
xmlsec1 --sign --output signed.xml --pkcs12 ia.p12 --pwd password --trusted-pem ca.crt to-sign.xml
And here is my signature info:
   <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">      <SignedInfo>         <Canonical tizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315" />         <SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1" />         <Reference URI="">            <Transforms>               <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature" />               <Transform Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315" />            </Transforms>            <DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" />            <DigestValue></DigestValue>         </Reference>      </SignedInfo>      <SignatureValue></SignatureValue>      <KeyInfo>         <X509Data></X509Data>      </KeyInfo>   </Signature>
It's working but I get two X509Certificate tags:

Does anybody know why it's happening? I'm expecting only one X509Certificate tag.
Any tip will be very helpful,Thanks.
