The XML documents exchanged by CMS components via the XML Interface are called Payloads. The
ses-payload element is the root element of all request and response documents:
<!ELEMENT ses-payload (ses-header, (ses-response+ | ses-request+))> <!ATTLIST ses-payload payload-id CDATA #REQUIRED timestamp CDATA #REQUIRED version CDATA #REQUIRED >
The attributes of
ses-payload elements have the following
payload-idis generated by an algorithm.
In a request a client indicates which version of the XML Interface
protocol it is using by specifying a value for
The Search Engine Server supports – in addition to the current version of the protocol – all versions which were previously valid. If the client is using one of these versions, the server creates a response payload in this version. Otherwise, it responds with an error message which indicates the protocol incompatibility. The server creates this message in its current version of the XML Interface protocol.
