Spell Checker Dictionaries

Starting with Version 2011r3 Altova XMLSpy, StyleVision, and Authentic include a completely new spell checker that provides support for more languages, as well as extended support for language peculiarities. This is the same highly acclaimed spell checker that is also used by Google Chrome, Mozilla Firefox, OpenOffice, and MacOS X. The new spell checker is compatible with the OpenOffice dictionaries.

The selection of built-in dictionaries that ship with Altova software does not constitute any language preferences by Altova, but is largely based on the availability of dictionaries that permit redistribution with commercial software, such as the MPL, LGPL, or BSD licenses. Many other open-source dictionaries exist, but are distributed under a more restrictive licenses, such as the GPL license. Many of these dictionaries are available as part of a separate installer located below. It is your choice as to whether you can agree to the terms of the license applicable to the dictionary and whether the dictionary is appropriate for your use with the software on your computer.

In its standard configuration the spell checker in Altova software ships with 12 built-in languages and corresponding licenses, as indicated below.
