1The Batch Wizard lets you easily check multiple files and/or URLs. It will generate a neatly formatted HTML report with the results (view sample report). It can also check URLs and follow the links in the URLs to check an entire small to medium sized web site or part of a large one. The Batch Wizard is not included in the Home edition.
2The Configuration Editor lets you customize the validator messages, letting you change the text of many messages. You can also change the message type (for example, you can change a warning message to an error message). The Configuration Editor also lets you add your own validation messages, as well as new tags and attributes. The Configuration Editor is not included in the Home edition.
3The Pro edition allows you to specify a text file that contains special 'user functions' that are used during validations to customize the validation. These functions can be used to alter validation behavior and validation messages, perform additional checks, produce specialized output, and much more. Visit the TNPL section in the documentation for more information.
4The Pro edition can output validation messages in XML format. The Home edition cannot.
5Upgrade protection gives you a free major upgrade if a new major release becomes available within the upgrade protection period. A major upgrade is a change in version number of .1 or more, like from v24.0x to v25.0x. Upgrade pricing after the upgrade protection period can be found on the upgrade page.
Upgrades are available to upgrade your edition by paying the difference in price.
