Just need to know it, semantically. So most Linux/BSD systems using the X windows manager are using these layouts. For example, the "US International with dead keys" is quite different in X from the Windows implementation. So is the official names for these layouts are the "X keyboard layouts"or something?
Edit for clarification: I'm interested in the layouts's name for not machine, but for human consumption. For example, in Windows you have the English, United Stated Dvorak, English, United States International, English, United Kingdom, German, etc. layouts. And they are all called the Windows variants(?) of said layouts, though I'm not sure, perhaps there is an international standard for these layouts which Microsoft or X.org may or may not follow, I don't know, that's why I ask, thank you.
