as far as this and other complaints goes that we could submit as
official W3C comments, I would almost prefer if you, Dimitre,
or David would write up such a comment. Dimitre has in the past
exposed some weaknesses in my argumentation :-) and so, my words
may not be as effective as yours. I am ready to help and sign
a petition and I have contacts to a voting member of the working
group.
I am also copying Michael for the fairness. Michael has spoken in
favor of some type safety and I trust him a lot, certainly he is
not someone who could be accused of trying to throw sand into the
gears of XSLT. I could see how parameter polymorphism would work
nicely even with automatic type casting. First one would attempt
at matching an function's implementation against the actual argument
types and only if no complete match exists, conversion would
be done on those actual arguments that do not macth the type of
the corresponding formal argument. The whole thing could be
disambiguated by a match score that would be
n
score:=SUM(likeness(type(formalArg[i]), type(actualArg[i])) * (n - i))
i=1
with n being the number of arguments, and the "likeness" function
between types being something that makes double and int more
related than double and boolean. Also I have factored in the
position of the argument just for the fun of it. This may be a
totally off base solution to the polymorphism issue. If so, forget
it and suggest a better one.
I am very anxious of having the practical experience and
understanding of this group here influence the W3C working group.
There's got to be a way for ernest and sophisticated users to
have some influence even if against the Microsofts of this world.
regards,
-Gunther
