I can't say for sure without seeing the schema but I suspect
you are talking about unqualified local elements in a schema
with target namespace, e.g.:


<schema targetNamespace="test"
        xmlns:t="test"
        xmlns="http://www.w3.org/2001/XMLSchema">

  <complexType name="type">
    <sequence>
      <element name="foo" type="string"/>
    </sequence>
  </complexType>

  <element name="bar" type="t:type"/>

</schema>


In the schema above, element 'bar' is in the 'test' namespace while
local element 'foo' is not in any namespace (which is in the XSD-
generated code is indicated by an empty string). If you want local
elements like 'foo' to also be qualified, then you will need to add
elementFormDefault="qualified" to the schema declaration:

<schema targetNamespace="test"
        xmlns:t="test"
        xmlns="http://www.w3.org/2001/XMLSchema"
        elementFormDefault="qualified">

  ...

</schema>
