In a rather stange looking schema you could. For example: <schema> <simpleType name="PersonNameType"> <restriction> <!-- put your restrictions here, like length and stuff --> </restriction> </simpleType> <element name="Person"> <complexType> <choice> <sequence> <element name="PersonName"> <complexType> <simpleContent> <extension> <attribute name="value" type="PersonNameType"/> </extension> </simpleConent> </complexType> </element> <!-- Add all your other *attribute* elements here --> </sequence> <sequence> <element name="PersonName" type="PersonNameType"/> <!-- Add all your other *element text* elements here --> </sequence> </choice> </complexType> </element> </schema> This sort of schema would in effect do what you're looking for, making all the nodes have either a "value" attribute, or the text of the element having the value. The only restriction is that you couldn't do this to the document element, since there's no way to "choice" a document element with the same name. It's an ugly schema, IMHO, but would work. Bryce K.

I want to define restriction that data (person name itself) may be defined either in "value" attribute or as element text. Meaning - either this way: <PersonName value="John Doe"/> or this way: <PersonName> John Doe </PersonName> But this is forbidden: <PersonName value="John Doe"> Jane Smith <PersonName> I have been reading spec, tutorials, references, I have been gooooooooogling for hours but I can't find out how to do this or even if it is feasible at all. Please - can this restriction be defined using XML schema? If so, how? Can anyone provide an example? thnx -- Patrik Beno mailto:pb@p... ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://www.oasis-open.org/mlmanage/index.php>
