We've covered a lot of ground in this chapter regarding Word's support for and integration with XML.

Microsoft InfoPath is a new product in the Microsoft Office System. Microsoft InfoPath was designed with teams and organizations in mind whose main purpose in their job is to collect and use information. Easy creation of powerful input forms that include business logic validation, auto correction, spell checking, and rich-text formatting as a front end to XML data sources are the strength of Microsoft InfoPath.
Consider using Microsoft InfoPath or another tool if
You need fast and efficient data input
You frequently need to build front-end forms for data input
You need rich-text forms style formatting
You need business logic validation
You need automatic data-source updating without having to worry about file formats (that is, WordML versus data-only XML)
