New to XML Schema. I am writing the entire schema with the prefix of xs: but when I tried to insert the following I rcvd an error saying it was not valid with the schema but then I change it to the prefix of xsd: the error went away but the rest of the schema still has the prefix of xs:
ANY IDEAS!!!!!!!!!!

<xs: simpleType>
<xs: enumeration value="small"/>
</xs:simpleType>

Thank You

Hi,

Sure you should get errors with the following schema:

Code: Select all


<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType>

    <xs:enumeration value="small"/>

  </xs:simpleType>

</xs:schema>

The simpleType element defines a global simple type. You need to specify a name for the global symple type as you can see in one of the errors you get:

E s4s-att-must-appear: Attribute 'name' must appear in element 'simpleType'. test.xsd file:/D:/test/test.xsd 3:18

Also you cannot place enumeration directly inside a simple type, you can restrict for instance the string type to contain only the "small" string as value, like below:

Code: Select all


<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType name="test">

    <xs:restriction base="xs:string">

      <xs:enumeration value="small"/>

    </xs:restriction>

  </xs:simpleType>

</xs:schema>

I'm not sure what happens when you use xsd as prefix, you should post a full sample so we can have a look. Anyway, I get for instance an error for:

Code: Select all


<?xml version="1.0"?>

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xsd:simpleType name="test">

    <xsd:enumeration value="small"/>

  </xsd:simpleType>

</xs:schema>

F The prefix "xsd" for element "xsd:simpleType" is not bound. test.xsd file:/D:/test/test.xsd 3:31

Best Regards,
