+**Unicode MessageFormat** is sometimes referred to as _MessageFormat 2.0_,
+since it replaces earlier message formatting capabilities built into ICU.
 
 Some _default functions_ and items in the `u:` namespace are still in Draft status.
 Feedback from users and implementers might result in changes to these capabilities.

+This section defines a data model representation of Unicode MessageFormat _messages_.
 
 Implementations are not required to use this data model for their internal representation of messages.
 Neither are they required to provide an interface that accepts or produces
 representations of this data model.
 
 The major reason this specification provides a data model is to allow interchange of 
 the logical representation of a _message_ between different implementations.
-This includes mapping legacy formatting syntaxes (such as MessageFormat 1)
-to a MessageFormat 2 implementation.
+This includes mapping legacy formatting syntaxes (such as ICU MessageFormat)
+to a Unicode MessageFormat implementation.
 Another use would be in converting to or from translation formats without 
 the need to continually parse and serialize all or part of a message.
 
 Implementations that expose APIs supporting the production, consumption, or transformation of a
 _message_ as a data structure are encouraged to use this data model.
 
 This data model provides these capabilities:
-- any MessageFormat 2.0 message can be parsed into this representation
+- any Unicode MessageFormat _message_ can be parsed into this representation
 - this data model representation can be serialized as a well-formed
-MessageFormat 2.0 message
-- parsing a MessageFormat 2.0 message into a data model representation
+  Unicode MessageFormat _message_
+- parsing a Unicode MessageFormat _message_ into a data model representation
   and then serializing it results in an equivalently functional message
 
 This data model might also be used to:
-- parse a non-MessageFormat 2 message into a data model
-  (and therefore re-serialize it as MessageFormat 2).
+- parse non Unicode MessageFormat messages into a data model
+  (and therefore re-serialize it as Unicode MessageFormat).
   Note that this depends on compatibility between the two syntaxes.
-- re-serialize a MessageFormat 2 message into some other format
+- re-serialize a Unicode MessageFormat _message_ into some other format
   including (but not limited to) other formatting syntaxes
   or translation formats.
