The nullable flag of a stored procedure parameter seems to be wrong [DNET335] #346
Submitted by: Alexander Muylaert (alexander_gonline.be)
I was having an argument with the guys from llblgenpro. They said that there is no way to know if a stored procedure parameter is nullable or not. I disagreed, since in firebird this seems to work. I tried proving them wrong.
I made a stored procedure that contains all possible declarations of a parameter to me.
create procedure SMURF (
and then I asked for the schema information.
Attached you'll find the test.xml. It looks to me that the syntax used for IN_NOT_NULLABLE_BOOL3 doesn't return the correct flag for IsNullable.
is this something fixable?

If I think about it.
IN_NOT_NULLABLE_BOOL2 type of D_BOOL_NN,
This is marked as "not nullable" when actually it is.
You can put null types inside this parameters, hence the syntax of type of.
If you decide to fix the first part, maybe you can fix the second part to?
