It's the first time I've had to define anything like this myself and it's going to be used as an input to an application I'm writing so i'd like to use best practices from the start.Craig.
  4. Thank you for your reply... i am using XML Spy to validate the XML and it didn't get as far as stating that i forgot the units part With regards to the choice section i believe we are misunderstanding what i wish to achieve.I wold like the port node to contain either a single element called <FREQ_MASTER> or three elements called <START_FREQ>, <STOP_FREQ> and <POINTS>.So the XML file i showed above has two different contents for PORT, of which both should be valid... i just can't get the schema to adhere to my desires.With regards to your comment about the , can you expand upon which elements would require this?Thank you once again for taking the time to assist.Craig.
  5. It is possible, instead of this line: <xs:attribute name="date" type="xs:date" use="required" form="qualified"/> you need to have something like this: <xs:attribute name="date" type="carType" use="required" form="qualified"/> then add this section somewhere: <xs:simpleType name="carType"> <xs:restriction base="xs:string"> <xs:enumeration value="Audi"/> <xs:enumeration value="Golf"/> <xs:enumeration value="BMW"/> </xs:restriction></xs:simpleType> Obviously carType is not what you need, but it's an example lifted right off the w3schools website...http://www.w3schools.com/schema/schema_facets.aspCraig.[edit]oh man! sorry i didn't realise how old this topic was... sorry the assistance is so late in coming, i presume you'd have sorted it by now[/edit]

  7. At first glance you are missing the XML declaration at the start of your schema.http://www.w3schools.com/schema/schema_howto.asp scroll down to get to the title "An XML Schema"
