LDML47-Stable

LDML47 is the first stable release of the MessageFormat specification.

Changes in this release (from 46.1) include:

Made MessageFormat stable and made the stability policy normative.
Added or clarified terminology:
- Linked all terminology in the MessageFormat section to the term's definition.
- Defined option value, literal key, string value, and digit size option formally. Other definitions were defined or modified for clarity.
- Replaced the concept of a "function registry" with default functions and u: namespace functions and options.
- Changed the data model to be called the "Interchange Data Model"
Modified portions of the syntax (ABNF)
- Removed number-literal from the ABNF and moved its definition to the default functions for numeric formatting.
- Changed (expanded) the range of characters allowed in an unquoted literal and simplified syntax character set definitions.
Revised the Default Bidi Strategy.
Enabled functions to know whether an option value was set using a literal or a variable, which is necessary for some function's selection mechanism (see below).
Updated the default functions:
- Only three default functions are stable: :string, :number, and :integer. Other functions are Draft.
- Some options have been removed, modified, or made optional.
- The select option on :number and :integer functions now accepts only literal values.
- Removed the style percent from :number and :integer pending future standardization.
- The u: namespace options u:id and u:dir are optional; u:locale is Draft.
Clarified how to include the character "*" in a key.
