+Formatter registry
+------------------
+
+The `formatters` registry contains functions to format values. Each formatter 
+has the following API:

+.. js:function:: format(value[, options])
+
+    :param value: a value of a specific type, or `false` if no value is given
+    :type value: T | false
+    :param Object options: various options

+Parser registry
+---------------

+The `parsers` registry contains functions to parse values. Each parser 
+has the following API:
+
+.. js:function:: parse(value[, options])

+
+    :param value: a string representing a value
+    :type value: string

+
+    Parses a string and returns a value. If the string does not represent a valid
+    value, parsers can fail and throw errors.
