A representation of the XML SignatureMethod element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. The XML Schema Definition is defined as:

  <element name="SignatureMethod" type="ds:SignatureMethodType"/>
    <complexType name="SignatureMethodType" mixed="true">
      <sequence>
        <element name="HMACOutputLength" minOccurs="0" type="ds:HMACOutputLengthType"/>
        <any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>
          <!-- (0,unbounded) elements from (1,1) namespace -->
      </sequence>
      <attribute name="Algorithm" type="anyURI" use="required"/>
    </complexType>
A SignatureMethod instance may be created by invoking the newSignatureMethod method of the XMLSignatureFactory class.
