[xmlsec] How to avoid the node passed to xmlSecEncCtxXmlEncrypt to be released

[Frank Gross]

Hi,

  I noticed that function 'xmlSecEncCtxXmlEncrypt' releases the node 
that was encrypted when replaced by the 'EncryptedData' node.
Does it exist a way to not release that node, and let the user choose 
whether he wants to destroy it or not ?

Thanks,

Frank
