In what useful way does that differ from what's already supported (LRM
4.4)?

Once extended RTTI is supported, the current attribute support (which
only works for types) will be extended to fields as well:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i type  //
assumes that there is a JSONAttribute type that descends from
TCustomAttribute  TEmployee = record    [JSON('firstname')]   
FirstName: String;    [JSON('lastname')]    LastName: String;   
[JSON('city')]    City: String;  end;
They can then be accessed using Attributes property of the
corresponding types in unit Rtti.

I presume the second field is named "LastName" instead of FirstName
(otherwise the compiler would rightfully complain about a duplicate
identifier.)

Yes, obviously.  Thank you for the correction (I fixed it now)
