Problems with XmlSchema name mangling XmlSchemaSet compilation

[Ryan]

Hello Xml Gurus,

I'm trying to build an XML schema in memory using the System.Xml.XmlS chema
namespace objects, validate it, and then write it to a file. The problem
I'm facing is that XmlSchema.Write () is changing

<xsd:element minOccurs="1" name="AccountId " type="s-xsd:primarykey" />

to be

<xsd:element minOccurs="1" name="AccountId " xmlns:q1="s-xsd"
type="q1:primar ykey" />

and I am also getting the following error messages by XmlSchemaSet.Co mpile()

Namespace 's-xsd' is not available to be referenced in this schema.
Type 's-xsd:primarykey' is not declared.
--------------------------------------------------------------------------------
My code basically looks like this
--------------------------------------------------------------------------------

XmlSchema schema = new XmlSchema();
schema.Attribut eFormDefault = XmlSchemaForm.U nqualified;
schema.ElementF ormDefault = XmlSchemaForm.Q ualified;
schema.TargetNa mespace = "http://www.baseUri.com/sxml/1.0";
schema.Namespac es.Add("xsd", "http://www.w3.org/2001/XMLSchema");
schema.Namespac es.Add("s-xml", "http://www.baseUri.com/sxml/1.0");
schema.Namespac es.Add("s-xsd", "http://www.baseUri.com/sxsd/1.0");

// <xsd:import.. .
XmlSchemaImport import = new XmlSchemaImport ();
schema.Includes .Add(import);
import.Namespac e = "http://www.baseUri.com/sxsd/1.0";
import.SchemaLo cation = "s-xsd.xsd";

// <xsd:complexTyp e...
XmlSchemaComple x complexType = new XmlSchemaComple xType();
schema.Items.Ad d(complexType);
complexType.Nam e = "Account";

// <xsd:sequence >
XmlSchemaSequen ce sequence = new XmlSchemaSequen ce();
complexType.Par ticle = sequence;

// <xsd:element. ..
XmlSchemaElemen t element = new XmlSchemaElemen t();
element.Name = "AccountId" ;
element.MinOccu rs = 1;
element.MaxOccu rs = 1;
element.SchemaT ype = new XmlQualifiedNam e("primarykey ", "s-xsd");

// Compile schema and validate
XmlSchemaSet schemaSet = new XmlSchemaSet();
schemaSet.Valid ationEventHandl er += new
ValidationEvent Handler(schemaS et_ValidationEv entHandler);
schemaSet.Add(s chema);
schemaSet.Compi le();

// Write compiled schemas to output
foreach (XmlSchema compiledSchema in schemaSet.Schem as())
{
XmlNamespaceMan ager nsmgr = new XmlNamespaceMan ager(new NameTable());
nsmgr.AddNamesp ace("xsd", "http://www.w3.org/2001/XMLSchema");
nsmgr.AddNamesp ace("s-xml", "http://www.baseUri.com/sxml/1.0");
nsmgr.AddNamesp ace("s-xsd", "http://www.baseUri.com/sxsd/1.0");
compiledSchema. Write(Console.O ut);
}

--------------------------------------------------------------------------------
And the output looks like this:

(Note that there are 2 schemas. The first is the one I
created through code, and the second is the one
referenced by the first)
--------------------------------------------------------------------------------

<?xml version="1.0" encoding="IBM43 7"?>

<xsd:simpleTy pe name="primaryke y">
<xsd:restrictio n base="xsd:strin g" />
</xsd:simpleType>
</xsd:schema>

Can someone please tell me what I'm doing wrong? Is the
System.Xml.XmlS chema more pain than it's worth?

Thanks,

Took a break then came back and quickly realized my stupid mistake...

element.SchemaT ype = new XmlQualifiedNam e("primarykey ", "s-xsd");

should have been

element.SchemaT ype = new XmlQualifiedNam e("primarykey ",
"http://www.baseUri.com/sxsd/1.0");

That took care of both the aliasing (which now makes sense because it had to
use local scope to override a global namespace naming collision) and the
errors output from XmlSchemaSet.Co mpile()
