 ### `Code`
 
 `Code` ([`Text`][text]) occurs at block level (see
-[`InlineCode`][inlinecode] for code spans).  `Code` supports an
-info string and a language tag (when the line with the opening fence
-contains some text, it is stored as the info string, the first word
-following the fence is stored as the language tag, the rest of the
-line is stored as the info string, both are null if missing)

+of fenced code can be followed by a language tag, and then optionally
+white-space followed by the meta value.
