+- Updated obsolete RFC 4646 reference to RFC 5646 (BCP 47).
+- Fixed terminology: `$uses` is an array, not a "clause"; entries are not
+  "keys".
+- Removed awkward parenthetical "(property)" in `has` keyword definition.
+- Clarified roles of `patternProperties`/`patternKeys` vs
+  `propertyNames`/`keyNames`: the former validates property values by name
+  pattern, the latter validates names themselves.
