Expression Web Designer will include reporting and management tools. Designers can get reports on whether Cascading Style Sheets on a site are resulting in errors, whether the site is accessible to handicapped Web users and how many errors users of older Web browsers are encountering when viewing the site, said Smith.

Expression Web Designer is expected to be released by year's end, Smith said. The other two Expression tools, because they rely on technologies in the Windows Vista operating system, won't be released until 2007 at the earliest.
