# Interface SignatureProperties

All Superinterfaces:
  `XMLStructure`

public interface SignatureProperties extends XMLStructure
A representation of the XML `SignatureProperties` element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. The XML Schema Definition is defined as:

    <element name="SignatureProperties" type="ds:SignaturePropertiesType"/>
       <complexType name="SignaturePropertiesType">
         <sequence>
           <element ref="ds:SignatureProperty" maxOccurs="unbounded"/>
         </sequence>
         <attribute name="Id" type="ID" use="optional"/>
       </complexType>

A `SignatureProperties` instance may be created by invoking the `newSignatureProperties` method of the `XMLSignatureFactory` class; for example:

       XMLSignatureFactory factory = XMLSignatureFactory.getInstance("DOM");
       SignatureProperties properties =
          factory.newSignatureProperties(props, "signature-properties-1");
