RSA sign fail on xmlsec verify.

I am using the class RSAKey to sign XML documents and then check using the 
utility XMLSEC (http://www.aleksey.com/xmlsec). But the value of the signature 
never matches the amount signed by xmlsec in a test environment.

What steps will reproduce the problem?
1. Use the file "publicKey" to sign the string contained in "dataToSign.xml.

2. Use the following code to calculate the digital signature:
var src:ByteArray = Hex.toArray(Hex.fromString(dataToSignContent));
var dst:ByteArray = new ByteArray();        
var hash:SHA1 = new SHA1(); 
src = hash.hash(src);
var rsa:RSAKey = PEM.readRSAPrivateKey(key);
rsa.sign(src, dst, src.length);
var signatureValue:String = Base64.encodeByteArray(dst);

3. Use XMLSEC to sign "unsigned.xml" file 
(on command line use "xmlsec1 sign --privkey private.key --output signed.xml 
unsigned.xml").

What is the expected output? What do you see instead?

It is expected that the value of the variable signatureValue (in code above in 
AS3) has the same value produced by xmlsec ie:

What version of the product are you using? On what operating system?

I used all the versions of as3crypto, but my tests are with the latest version 
1.3 revision 28. Using FlashBuilder 4 (Flex 4.1.0) in Windows7 64x for signing 
the XML. To verify the signature using FreeBSD8 and/or Ubuntu10 with xmlsec1.

Please provide any additional information below.

In my application I use XML documents also signed with HMAC-SHA1 in XML 
canonicalized and everything works fine (with as3crypto and xmlsec). So I 
assumed that there were no problems in the process of canonicalization. I'm 
working for two months in this role and I can not have any more idea what to do.
