XML validation against XSD that includes more XSDs: type is not declared

I have a problem in validating XML against XSD when the base XSD is importing some other XSDs from site. For example, for the following XSD item, it is throwing error.

<link:linkbase xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:link = 'http://www.xbrl.org/2003/linkbase' xmlns:xbrli = 'http://www.xbrl.org/2003/instance' xmlns:xlink = 'http://www.w3.org/1999/xlink' xsi:schemaLocation = 'http://www.xbrl.org/2003/linkbase http://www.xbrl.org/2003/xbrl-linkbase-2003-12-31.xsd' >

Is there any solution for importing the XSD by release version of DLLs. I am using the following C# code for validating XML against the XSD. The same is working when I execute it through Visual Studio.

var schemas = new XmlSchemaSet();
schemas.Add(null, xsdFilePath);

var readerSettings = new XmlReaderSettings();
readerSettings.ValidationType = ValidationType.Schema;
readerSettings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
readerSettings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
readerSettings.Schemas.Add(schemas);

using (var xmlReader = XmlReader.Create(xmlFilePath, readerSettings))
{
    while (xmlReader.Read())
    {
    }  
}

Obviously, the parser cannot find the schema xbrl-instance-2003-12-31. From the w3 schema specs:

(xsi:schemaLocation) records the author's warrant with pairs of URI references (one for the namespace name, and one for a hint as to the location of a schema document defining names for that namespace name)

that is, the first part of your schemaLocation definition xbrl.org/2003/xbrl-instance-2003-12-31.xsd is the namespace. If the parser doesn't already know where to find the schema for such namespace, you must provide it with the location. For example:

<xs:import
    namespace='xbrl.org/2003/instance'
    schemaLocation='xbrl.org/2003/xbrl-instance-2003-12-31.xsd http:/xbrl.org/2003/xbrl-instance-2003-12-31.xsd'/>
