Imported namespace conflicts with a target namespace

[navozenko]

Hi. I found a problem with schema generation for arrays of system types. In the resulting schema, the name of the targetNamespace is the same as the name of one of the imported namespaces. This causes a validation error in some applications.

<xs:schema elementFormDefault="qualified"
           targetNamespace="http://schemas.datacontract.org/2004/07/System"
           xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:tns="http://schemas.datacontract.org/2004/07/System"
           xmlns:ser="http://schemas.microsoft.com/2003/10/Serialization/">
  <xs:import namespace="http://schemas.datacontract.org/2004/07/System" />
  <xs:import namespace="http://schemas.microsoft.com/2003/10/Serialization/Arrays" />
  <xs:complexType name="ArrayOfByte" xmlns:ser="http://schemas.microsoft.com/2003/10/Serialization/">
    <xs:sequence>...</xs:sequence>
  </xs:complexType>
  ...
</xs:schema>

Could we disable namespace import if it matches the targetNamespace?
