Hi There,<BR><BR>What&#039;s the drawback to use XML to pass data between components, comparing to use Disconnected ADO record set?<BR><BR>What&#039;s the drawback if defining all components that have a single method which accepts XML as input parameter and returns XML representing the output. This XML contains component name, method name, input data, array values and even ADO rerecord set data.<BR><BR>Thanks in advance,<BR><BR>John<BR><BR><BR><BR><BR>
