* Prior to this code, we created N signed SOAP messages, each containing a single signed record.
* Load each of these signed SOAP messages into a StringBuilder and insert after the "</sum:Cabecera>"
* Note: We must NOT use Chilkat.Xml for this.  We must do string operations using Chilkat StringBuilder to prevent whitespace or formatting modifications which would break the signatures.
