+ * Class used to hide mw:editsection tokens from Tidy so that it doesn't break them
+ * or break on them. This is a bit of a hack for now, but hopefully in the future
+ * we may create a real postprocessor or something that will replace this.
+ * It's called wrapper because for now it basically takes over MWTidy::tidy's task
+ * of wrapping the text in a xhtml block
+ *
+ * This re-uses some of the parser's UNIQ tricks, though some of it is private so it's
+ * duplicated. Perhaps we should create an abstract marker hiding class.
