RFI | Server side .NET XForms Engine/Processor

[kris]

Hi All,

We have an opportunity to evaluate Server side .NET XForms engine for
processing multiple SED (Structured Electronic Document).

We are looking for following basic functionality in XForms Processor:-

The XForms User Interface must provides standard set of visual
controls (GUI element, button, textbox, checkboxes) that are targeted
toward replacing XHTML form controls. These form controls are directly
usable inside XHTML and other XML documents.

XForms provides functionality to collect form data, which is expressed
as XML instance data, should describe structure of the instance data.

Nice to have support for workflow, auto-fill, and pre-fill form
applications are through the use of instance data.

Has anybody worked upon similar type of implementation in past or any
pointer where Server side .NET based Xform processor implemented?

Your input will be highly appreciated.
