Low-end Office 11 won't do user schemas, it seems

http://news.com.com/2100-1012-996528.html says that the low-end version of
Office 11 won't do custom schemas, unlike the beta release and the 
Professional and Enterprise versions.  The built-in schema will still
be available in the low-end version, but it has not been fully documented.

In addition, InfoPath will be available only in the high-end version, which
requires Licensing 6.0 (large companies only, and pay-to-play).
