Please do consider these two XML document variants and related explanations: 1. <x xmlns="http://ns1"> <y/> </x> Here the outermost element and all included elements are in namespace, and this can be specified by elementFormDefault="qualified" definition in schema document. 2. <ns1:x xmlns:ns1="http://ns1"> <y/> <y/> </ns1:x> Here only the outermost element is in a namespace, but inner ones are not in namespace (the inner elements are in no/null namespace). These document constraints can be specified by elementFormDefault="unqualified" (and this is available by default in a schema document, if not specified by schema author). I personally do not agree that only elementFormDefault="qualified" should exist (either by syntax or implicitly available by language design) in XML schema language. Allowing schema authors to specify either "qualified" or "unqualified" for elements (and also for attributes) is a significant design made into the XML Schema language (and i personally do find this OK :) -- Regards, Mukul Gandhi
