xsd.exe question

[Schemer]

Hello,

I am trying to use xsd.(Version 2.0.50727.42) exe to generate classes from a
schema. My schema begins like this:
<?xml version="1.0" encoding="utf-8"?>
<schema targetNamespace="http://www.myCorp.com/wfs"
xmlns:miwfs="http://www.myCorp.com/wfs"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:gml="http://www.opengis.net/gml"
elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema">
<xs:import namespace="http://www.opengis.net/wfs"
schemaLocation="http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd" />
<xs:element name="USA" type="miwfs:USA_Type"
substitutionGroup="gml:_Feature" />
<xs:complexType name="USA_Type">
<xs:complexContent>
<xs:extension base="gml:AbstractFeatureType">

When I run
xsd.exe -c -l:c# usa.xsd

I get these errors:
[Microsoft (R) .NET Framework, Version 2.0.50727.42]
Copyright (C) Microsoft Corporation. All rights reserved.
Schema validation warning: Undefined complexType
'http://www.opengis.net/gml:Abstrac
tFeatureType' is used as a base for complex type extension. Line 9, position
14.
Schema validation warning: Reference to undeclared substitution group
affiliation. L
ine 6, position 6.

Warning: Schema could not be validated. Class generation may fail or may
produce inc
orrect results.

Error: Error generating classes for schema 'usa'.
- The datatype 'http://www.opengis.net/gml:AbstractFeatureType' is
missing.

Does the schema need to import the entire gml schema to fix this? Or is
there some other problem?

Thanks for any insight....

Hi Schemer,

In order to include the type in another namespace in another .xsd file, you
have to

1. Import the file using <import>
2. add the source file in the xsd.exe command line, like

xsd importedAttribute.xsd attributeRef.xsd /classes /language:CS
