TitleVallidity error: elements out of order
DescriptionAn XHTML file that is well-formed but not valid because the the first definition dd element ("definition description") appears before the first dt, which is not allowed by the specification. As a consequence, the first definition appears before the term that it defines. Validity is a requirement for 'Strictly Conforming Documents' (see http://www.w3.org/TR/2002/REC-xhtml1-20020801/#strict).
