I'm ashamed to say that office2003 has been using it for a few months, but I don't know that it contains a killer.
I always wanted to create a tool: automatically generate the UI Based on the schema.
Such a tool can directly read the WSDL to construct the user input interface and construct the result screen. Using this technology, it is quite comfortable to reference WebService in applications. Now, at least import the image and create your own user image. Maybe we can apply different styles like DataGrid...
Many problems encountered during implementation. At that time, Java had poor support for schema parsing, And the dom3 model had not yet been introduced. Then it becomes dream.
In terms of thinking, infopath is indeed innovative. The XSL and Schema are completed at the same time during the design.
In terms of use, the availability is good. Create a new line and a tree representation... The final archive is pure XML
Import existing schema directly or specify the WSDL to design a document that works closely with ws. This document is an application. After being submitted to WS, WS calls the workflow engine for forwarding and processing.
If you embed infopath into the browser, enter the form online and send it. It should be the fate of OA.
