While most citations simply provide the bibliographic information for a cited reference, a few describe the work, categorize the work, comment upon the nature or quality of the work, or summarize its findings. The <annotation> element is intended to hold such commentary.
Display Note: All of the other reference elements are inline elements. In contrast, an <annotation> is typically presented as a block element, with space before and after it.
