How to display a Signature via the view1.xsl ?

[Bill N.]

I have a .Net web app that invokes a published InfoPath 2007 form. The end
user fills out and digitally signs the form, then submits it to a web
service, which among other actions, saves the form's XML to a DB and makes a
copy of the form XML available for download. I'm using the Source
querystring parameter and a custom redirector ASPX page to get back to my web
app on close...this works well for me so far.

I need to provide a viewing capability to the end user that shows the
signature. The view1.xsl is not displaying the signature despite my using
that workaround (i.e. including the <?xml-stylesheet type="text/xsl"
href="view1.xsl"?> instruction in the XML). The rest of the form displays
properly. I need this in order to support a large user community without
InfoPath. I also have an ESign requirement to make the saved XML file
available to the end user for storage on their PC. (Another way to express
this problem is: I want to display a *filled out and signed form stored as
XML* in the browser, but the XSL doesn't do so.)

Right now I'm working this problem as an XSL issue. Is this the right way
to proceed, or am I missing something?

OK, after further research, I think I have answered my questions.

The book "Pro InfoPath 2007" says words to the effect that XML files are
considered useless for users without an InfoPath installation. (Chapter 6,
p. 113 "Saving and Submitting")

I also found a post at
http://groups.google.com/group/micr...lnk=gst&q=function-available#88ed2e914dce3373 that says some of the formatting won't be available outside of InfoPath.

Since I still have my previous requirements, I'll work the XSL problem,
recreating the markup without using the (apparently) unavailable
xmlns:xdXDocument.

Still hoping for a magic bullet here, so feel free to comment.

OK, I'm dropping this in favor of my original PDF-based solution.

Trying to come up with all the functionality needed to support offline
viewing and validation of digital signatures in InfoPath forms stored by
end-users was not worth the effort to me compared with the out of the box
functionality provided by PDFs.
