XSD ERROR:

s4s-elt-must-match.1: The content of 'AccountDetailsResponse' must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: element.

Thanks in advance

Answer 1

Most likely you did not provided us with the entire input. From your schema, I would expect an element AccountDetailsResponse around the excerpt you posted.

As you figured out for the other elements, you cannot have an xs:element as a direct child of another xs:element. Most likely, using the same as you did for the other elements (an ordered sequence of children) would do what you want:

<xsd:element name="AccountDetailsResponse">
   <xsd:complexType>
      <xsd:sequence>
         <xsd:element name="ACCOUNTDETAILS" type="account:Account">
         ...

This will not work either, as you cannot have both a type attribute, and an embedded xs:complexType at the same time. So probably you will want to get rid of that one type attribute. So the following should work:

<xsd:element name="AccountDetailsResponse">
   <xsd:complexType>
      <xsd:sequence>
         <xsd:element name="ACCOUNTDETAILS">
         ...
