Sadly this forum doesn't have a very stable membership. People come to ask a question and then disappear. As a result, not many people are answering questions, and if those people happen to be busy on a particular day, it's not uncommon to get no answer. I try to answer XSLT questions when I can; but for some reason the forum seems to attract a high proportion of queries that are specific to Microsoft technologies, and I'm no expert in those areas.
You can use XSLT to generate any XML, HTML, or XHTML document and that of course includes one that uses XForms elements. You can do that whether or not your XSLT transformation is driven from ASP pages. But of course, there's no point generating XForms elements unless there is an XForms processor somewhere to handle them. That can be a client-side or a server side XForms engine - but if you want to know more about XForms, then an XSLT forum isn't the best place to ask.
