This element is used within an XML Signature KeyInfo tag to provide a pointer to a assertion/license that may be useful in determining the trust associated with an XML Signature. This element is used within licenseLocation to provide a URI to the assertion/license. This element defines the WS-Security credentials header. It's purpose is to encapsulate credentials that are agreed to between the SOAP producer and consumer. This header is designed to allow all valid SOAP attributes as well as other namespace qualified attributes that are appropriate in the context that this is being used within. This element defines the WS-Security integrity header. It's purpose is to encapsulate the XML digital signatures of the SOAP message that contains this header. This header is designed to allow all valid SOAP attributes as well as other namespace qualified attributes that are appropriate in the context that this is being used within. The use of "any" is to allow extensibility. It is expected that "Signature" elements from XML Signature be used here. This element defines the WS-Security confidentiality header. It's purpose is to identify encrypted parts or attachments. This header is designed to allow all valid SOAP attributes as well as other namespace qualified attributes that are appropriate in the context that this is being used within. The use of "any" is to allow extensibility. It is expected that "EncryptedData" elements from XML Encryption be used here. This attribute is used to identify the value space of the binary data. Its form and function is like that of xsi:type, except that it asserts a constraint on the type, not of the immediate contents, but the contents after decoding. This attribute is used to identify the binary encoding used for a credential/license. A license that is encoded in binary A credential that is encoded in binary
