Section 15.1 Functions and Operators on Sequences defines the functions zero-or-one(), one-or-more(), exactly-one(). The function definitions are: fn:zero-or-one($srcval as item*) as item? fn:one-or-more($srcval as item*) as item+ fn:exactly-one($srcval as item*) as item The main purpose of these functions is to raise an error if the property they name is not true for the parameter-sequence. Such functions are not necessary and useful, because, had their type been specified as: fn:zero-or-one($srcval as item?) as item? fn:one-or-more($srcval as item+) as item+ fn:exactly-one($srcval as item) as item then the error would be raised automatically if $srcval was not of the correct type. Such automatic errors would be raised for any function when passed parameters not matching the defined types of its arguments -- therefore the above three functions are not necessary at all. Solution: remove the functions fn:zero-or-one(), fn:one-or-more() and fn:exactly-one() Dimitre Novatchev __________________________________ Do you Yahoo!?
