XDocs

XDocs was a proposal announced by Microsoft on October 2002 for a forms software, based on XML. Only announcing vague details, it was supposed to help users design, modify and work with XML-based forms, with little or no coding. Unlike the W3C's XForms proposal, Microsoft would control the standard itself, which wasn't well received by the market. It was also a competitor to Adobe Systems's Forms Designer, which uses XML forms as well.

In 2003, Microsoft announced that XDocs was going to be known commercially as Microsoft InfoPath.
