While I agree with your statement about allowing/disallowing use of
'published' based on a directive, we inherited this from Delphi 
and it is a very basic part of the language & RTL, so changing it 
is simply not an option.

The extended RTTI is meant to remedy this (also in Delphi), 
but IMO it introduces its own problems (you'll love the amount 
of compiler directives it needs ;)).

I'm surprised to hear about your failure to get fcl-passrc to work, 
since it is used to create the docs based on the fpc sources. 
Additionally it forms the basis of pas2js, which fully supports all FPC constructs.

That said, I realize the (correct) use of fcl-passrc may be a bit hermetic...
