Re: [Exist-development] type-specific parameters in overloaded functions

[Dmitriy S. <sha...@gm...>]

Yes, eXist's xquery engine resolve function on name & number of parameters,
but do not put types in account. Well, it should be simple to improve ... do
you have svn access? If you haven't I can make one and make this changers &
you will test them (hope with others).
