1) There is no specification concerning the issues of XQuery DDL syntax and semantics so far. Are you planning to include CREATE and DROP document (and e.t.c.) statements to the update specification or this the subject for individual specification? 2) The "Changing values" functionality seems to be the potential cause of the appearance of the ambiguities during the document update: as far as changing the typed-value of the node doesn't uniquely determines the modification of the node' content. 3) "The XQuery Update Facility <http://www.w3.org/TR/xquery-update-requirements/#terminology-must> MUST be able to change the properties of existing nodes while preserving their identity". I guess it is very problematically to fulfil this property in some native XDBMS implementations, since such a properties of the node like 'parent' property is strongly connected to the node identity (for instance, when numbering scheme is used for node identification) Regards, Leonid Novak.
