Circular base type dependency

[leus]

Using the following schemas:

Schemas.zip

I'm trying to generate classes using the following command line:

xscgen --namespace=MyProject --separateFiles --output=../Generated --namingScheme=Direct DU_Wrapper_3.4.0_B324.xsd

Files seem to generate correctly, but I get a bunch of "Circular base type dependency" errors. Other than manually changing these definitions, what else can be done to fix this? Also, any options to #pragma disable warnings like CS8981 (lower case type names) , or an option to normalize only those special cases?

This occurs because of these definitions which are restrictions of themselves:

<xsd:complexType name="ASSET_DETAIL_EXTENSION">
	<xsd:complexContent>
		<xsd:restriction base="ASSET_DETAIL_EXTENSION">
			<xsd:sequence>
				<xsd:element name="MISMO" type="MISMO_BASE" minOccurs="0"/>
				<xsd:element name="OTHER" minOccurs="0">
					<xsd:complexType>
						<xsd:complexContent>
							<xsd:restriction base="OTHER_BASE">
								<xsd:sequence>
									<xsd:group ref="ULAD:grpASSET_DETAIL_EXTENSION"/>
								</xsd:sequence>
							</xsd:restriction>
						</xsd:complexContent>
					</xsd:complexType>
				</xsd:element>
			</xsd:sequence>
		</xsd:restriction>
	</xsd:complexContent>
</xsd:complexType>

I've added a check that just adds the fixed string "Redefinition" to the type name of the derived class if a circular definition is detected.
