[comp.lang.ada] Question on Abstract Syntax Tree

brock@tuvie (Inst.f.Prakt.Info 1802) (05/09/89)

I have a question concerning the abstract syntax tree in ADA:
Is it part of the standard, or standardized anywhere?
Can You give me some references about work on it? I believe there
has been some description language called Diana

Thanks in advance Ulrich
