I suppose we ought to say why each setting is in our GPRs! We can use
Ada-style comments (advice I'm not very good at taking myself).

You have a lot of settings there that I don't recognise.

For the Compiler, I set all standard warnings (except elaboration-order)
and styles, with normal optimisation:

  -gnatwaL -gnatqQafoy -O2

though I'm not sure about qQ.

I think -E belongs with the Binder, not the Builder. I specify debug
symbols with -g on the Builder.

XML/Ada is meant to be installed, which would I suppose create an
xmlada.gpr, then you'd either ensure that that was on your
ADA_PROJECT_PATH and say eg 
  with "XMLAda.gpr";
or
  with "/full/path/to/XMLAda.gpr";

(I don't know the actual file name!)

However, I see that for my XML/Ada-using project I've just said

  Home := external ("HOME");

  for Source_Dirs use
    (
     ".",
     Home & "/xmlada/**",
     Home & "/bc"
    );

ie all Ada source under ~/xmlada. Might have to be careful if there is
test source under there (this was with 2.1).
