[xmlsec] Applying Multiple Signatures

$ man xmlsec1

--id-attr[:<attr-name>] [<node-namespace-uri>:]<node-name>

adds attributes <attr-name> (default value "id") from all nodes 
with<node-name> and namespace <node-namespace-uri> to the list of known 
ID attributes; this is a hack and if you can use DTD or schema to 
declare ID attributes instead (see "--dtd-file" option), I don't know 
what else might be broken in your application when you use this hack.


Thus I would try something like
$ xmlsec1 --sign
   --id-attr:Id http://www.w3.org/2000/09/xmldsig#:Signature
   --node-id Second
   --privkey-pem rsakey.pem
   document-template.xml
