The Lightning [developer guide][1] is not very helpful on how to use Design tokens:
Tokens created in the defaultTokens bundle are automatically available in components in your namespace.
Ok, and what if I want to rename it or if another one is already using it? How would I then access them different from:
.THIS p {
font-family: token(myBodyTextFontFace);
font-weight: token(myBodyTextFontWeight);
}
