This makes > sense to me now. With function mapping enabled, if a function takes a singleton argument, and you pass in a sequence, your function will be called n times, where n is the length of the sequence. This is true even when n is 0. > > And, by similar logic, it will not throw an error because the function > requires a singleton parameter, and I have provided one, albeit the empty > sequence. And, since the empty sequence is a valid singleton (is that true) > it will not throw an error because the parameters are valid. Actually, empty sequence is never a valid instance of a singleton type. In cases like these the error fails to throw not because the parameter is valid, but because the function itself never gets called. This is easy to get mixed up. I still do at times. -m _______________________________________________ General mailing list General@developer.marklogic.com http://xqzone.com/mailman/listinfo/general
