Z:gnu-www-ja-w3c-patent--46adeb-One requirement for Free Softw/en

One requirement for Free Software is that users have the freedom to modify and redistribute it. But we can hardly consider that users have freedom to publish modified versions of the program if, for a part of the program's behavior, modification is prohibited. Thus, these &ldquo;field of use&rdquo; restrictions would prevent implementation of W3C standards as  Free Software.
