Info boxes contain helpful notes or additional information about the point under discussion (or for the Notes to Readers on the cover page, about the standard as a whole) that may be of special interest to the reader, such as alternate modeling approaches currently in development, or points of interest about specific rows in a sample dataset.
Alert boxes contain information that it is especially important to note. In general, anything inside an alert box should be borne in mind while reading and/or implementing the advice presented in the user guide.
