Xml validation ---- file system of PI ???

Question

hi all ,
     i read the xml validation concept of PI7.1 . iam unable to find any practical explanation about the following
"To validate the structure of a PI message payload, you should export the schemas from the ESR and save them in the file system of PI. "
save them in the file system of pi ... where does this mean to be stored ?.
will it be necessary for both the ADAPTER ENGINE & INTEG ENGINE VALIDATION?
Please give any other important aspect of this validation concept which u came across  during ur practical implementation
THANKS IN ADVANCE

Hi Netaji,
  Validating the XML documents is a new feature introduced in SAP NetWeaver Process Integration 7.1. The validation can be performed at two different locations - Integration Server or the Adapter Engine. Validations can be done in both synchronous and asynchronous operations.
In the synchronous scenario or using an adapter that can handle synchronous messages (e.g. HTTP and SOAP adapters), when a validation error occurs, the error message will be returned to the sender. In the case of asynchronous scenarios (e.g. file adapter), the error message will be logged to the SXI_MONITOR when the validation is done in the Integration Server or to the Runtime Workbench (RWB) when the validation is done in the Adapter Engine. In both cases, the messaging will be terminated with error.
Both Integration Server and Adapter Engine can be used for validating XML from the sender. However, only the Integration Server can be used to validate the XML when sending to the receiver. The XML validation configurations are done in either the Sender Agreement or the Receiver Agreement.
In the current release, as of PI 7.1, the XML schema (or XSD) to be used for the XML validation has to reside in a file directory under the JEE. The XSD file has to be explicitly copied into a specific directory, depending on where the validation is to be performed.
