XmlSchemaImport, XmlSchema's and derived type

[Rumen Traykov via .NET 247]

Have somebody had already the problem of having to write more than one XmlSchema,
where some of these schemas have imports to others and respectively derived types?
The imports cannot be resolved until I dont save all schemas to disk, but I cannot
do this because I get an error for the derived types(which have base types from schema
which is not written yet, so the import cannot be resolved).
How could I solve this problem? I dont need any resolving, just save them to disk.
By compiling when I give a null-value for the XmlResolver
schema.Compile(textWriter, null)
I dont get the warning for the import, but still have an error for the derived type.
I also cannot give a specific order of the schemas to be written, because there could
be cycles of derivation in these schemas.

Perhaps somebody can tell me, if it is possible to generate all my elements in one schema
but still keep the namespaces and have derivation from one namespace to other? (I guess not).

It would be pitty to leave the XmlSchema object model and just write strings to files.

Thanks in advance!

The imports can be resolved without actually loading the schema from disk if
you already have an XmlSchema object corresponding to the
import in memory.
//Create imported schema
XmlSchema importedSchema = new XmlSchema();
importedSchema.TargetNamespace="import";
XmlSchemaElement elem = new XmlSchemaElement();
elem.Name="importedElement";
importedSchema.Items.Add(elem);

//Create main schema
XmlSchema mainSchema = new XmlShcema();
mainSchema.TargetNamespace="main";

XmlSchemaImport imp = new XmlSchemaImport();
imp.Namespace = "import";
imp.Schema = importedSchema; ----> This attaches the imported schema to the
import in the main schema

//Now add the import to the mainSchema
mainSchema.Includes.Add(imp);
mainSchema.Compile(null);

If the above does not solve your problem, please attach a code sample and
the schemas that you are trying to compile.

HTH,
Priya
