Attributes and Elements
Attributes
| Attribute | Description |
|---|---|
Type |
Optional element. Specifies the algorithm type. WSE supports wsse:AlgCanonicalization, wsse:AlgSignature, wsse:AlgDigest, and wsse:AlgTransform. |
URI |
Optional element. Specifies the URI for the algorithm. |
wsp:Preference |
Optional element. Specifies the preference for this particular alternative. The preference is expressed as an xsd:int. The higher the value of the preference, the greater the weighting of the expressed preference. |
Child Elements
None
Parent Elements
| Element | Description |
|---|---|
Specifies the digital signature requirements for a SOAP message. |
Remarks
When the <Algorithm> element is not specified, only the algorithms required by the XML Signature specification are supported.
Example
The following code example defines a policy assertion named signed-body-Kerberos that requires the digital signing of the <Body> element, timestamp header, and all addressing headers by a KerberosToken. The policy file then specifies that all SOAP messages sent to the http://www.cohowinery.com/Service1.asmx endpoint must adhere to the policy assertion.
Note
This code example is designed to demonstrate WSE features and is not intended for production use.
