There are many candidates for useful additional functions - trigonometric functions are another category. I think quite a good way forward with these is to propose specifications for inclusion in the EXSLT library (see www.exslt.org), which many vendors are choosing to integrate into their products. Those specifications that prove popular with implementors and users can then migrate into the core library at some later stage. Michael Kay
