Another statement of interest in the standard guidelines.
If an element has an EMPTY content model DO use the minimized tag syntax permitted by XML (e.g., <br />). DO NOT use the alternative syntax (e.g., <br></br>) allowed by XML, since this may be unsupported by HTML user agents. Also, DO include a space before the trailing / and >.
Empty elements in the XHTML family include: area, base, basefont, br, col, hr, img, input, isindex, link, meta, and param.
