+ * This class is a discriminated union wrapper that can represents a:
+ * - signed integer [range: Value::minInt - Value::maxInt]
+ * - unsigned integer (range: 0 - Value::maxUInt)
+ * - double
+ * - UTF-8 string
+ * - boolean
+ * - 'null'
+ * - an ordered list of Value
+ * - collection of name/value pairs (javascript object)
+ *
+ * The type of the held value is represented by a #ValueType and
+ * can be obtained using type().
+ *
+ * Values of an #objectValue or #arrayValue can be accessed using operator[]()
+ * methods.
+ * Non-const methods will automatically create the a #nullValue element
+ * if it does not exist.
+ * The sequence of an #arrayValue will be automatically resized and initialized
+ * with #nullValue. resize() can be used to enlarge or truncate an #arrayValue.
+ *
+ * The get() methods can be used to obtain default value in the case the
+ * required element does not exist.
+ *
+ * It is possible to iterate over the list of a #objectValue values using
+ * the getMemberNames() method.
+ *
+ * \note #Value string-length fit in size_t, but keys must be < 2^30.
+ * (The reason is an implementation detail.) A #CharReader will raise an
+ * exception if a bound is exceeded to avoid security holes in your app,
+ * but the Value API does *not* check bounds. That is the responsibility
+ * of the caller.
