In XML Schema, you can add attributes to an element with simple content using an anonymous complex type as a child of the element declaration. Something like will work: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="foo"> <xs:complexType> <xs:simpleContent> <xs:restriction base="xs:string"> <xs:enumeration value="fizz"/> <xs:enumeration value="fuzz"/> </xs:restriction> </xs:simpleContent> <xs:attribute name="bar" type="Bar"/> </xs:complexType> </xs:element> <xs:simpleType name="Bar"> <xs:restriction base="xs:string"> <xs:enumeration value="glorp"/> <xs:enumeration value="glop"/> </xs:restriction> </xs:simpleType> </xs:schema> The syntax for RELAX NG (12 lines) is somewhat simpler than the XML Schema syntax (18 lines). For example: <element name="foo" xmlns="http://relaxng.org/ns/structure/1.0"> <attribute name="bar"> <choice> <value>glorp</value> <value>glop</value> </choice> </attribute> <choice> <value>fizz</value> <value>fuzz</value> </choice> </element> Here is a valid instance for both schemas, tested with MSV: <?xml version="1.0"?> <foo bar="glorp">fuzz</foo> Mike -----Original Message----- From: Morgan V.

Subject: schema content model question I have been attempting to create an XML Schema content model for an element like the following: - the element should contain text only, no subeleemnts (simpleContent?) - the permissable values of the element should be restricted to a list of enumerated string values - the element should also have attributes with values which are also restricted to list of enumerated string values. Is this possible? I have made several attempts which I will send if it is useful for discussion but I thought perhaps someone can just provide the answer. thanks, Morgan Cundiff Library of Congress ----------------------------------------------------------------- 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://lists.xml.org/ob/adm.pl>
