What's your view to interoperability if query expression uses datatype such as xsd:dateTime and operator for the query is not equality nor not-equality? How would an otherwise DAWG compliant server - which didn't support xsd:dateTime (assuming dateTime wasn't part of DAWG rec, which I hope it will be) - evaluate the expression? An error message quite simply? Janne -- Janne Saarela <janne.saarela at profium.com> Profium, Lars Sonckin kaari 12, 02600 Espoo, FinlandReceived on Wednesday, 9 June 2004 06:49:15 UTC
