SOAP sign more elements

[makita]

Hello, does heve anybode experience how to create a signature of more elements via XML::Compile::WSS ::Signature? This is my code:

my $wsa  = XML::Compile::SOAP::WSA->new(version => '1.0');
my $wsdl = XML::Compile::WSDL11->new("some.wsdl");
my $wss  = XML::Compile::SOAP::WSS->new(schema => $wsdl);

my $cert_obj   = Crypt::OpenSSL::X509->new_from_file($cert);
my $token  = XML::Compile::WSS::SecToken::X509v3->new ( certificate =>
+ $cert_obj,);

my $sig = $wss->signature(
            schema => $wsdl,
            token => $token,
            sign_types=>['wsa:Action','wsa:To', 'wsu:Timestamp', 'wsa:
+MessageID','SOAP-ENV:Body'],
            signer=>DSIG_RSA_SHA1,
            public_key => $cert,
            private_key =>$cert_pk,
);

My problem is that only 'SOAP-ENV:Body' is always signed as default even i set more types. Inside of source code I've found more parameters like sign_when and sign_put. Don;t know how to use it and documentation is very poor
