-* This class implements a Text_Wiki_Parse to find source text marked as a
-* definition list.
-* If a line starts with ';' or ':' it is considered a part of a definition
-* list. ';' indicates the term to be defined and ':' indicates its definition.
-* As in Mediawiki we also allow definition lists to only consist of one
-* item-type.
