We discussed this ages ago -- it is perfectly reasonable for an engine to provide means for (extension) steps to detect the absence of non-defaulted optional options, indeed since we allow non-defaulted optional options, it follows that engines which support extension steps _must_ provide such a means. If we weren't in CR, I would argue that this applies to steps defined with p:declare-step, so we should (have) provided an XPath extension function p:isBound or p:unbound or whatever. . . ht - -- Henry S.
