+### Unreleased
+
+* Accept `normalize` option for `<value>` tag. This allows to write
+  invalid values, on purpose, for example to test validation logic.
+* Fixed a bug that added extra text nodes. You would not encounter these if you always wrapped things in a `<value>` tag, that was running a normalization.
