// Usage: add importScript(User:Svick/HarvErrors.js); to Special:Mypage/skin.js // See also Wikipedia:Centralized discussion/Citation discussion#Technical discussion regarding Harvard Refs // This script works fine for Harvard references in tags, but for inline Harv. refs, // the error message shows up at the end of the paragraph in which the error is error = " Harv error: this link doesn't point to any citation. ";
