Prototype online Xsd valdiation

Welcome to my prototype online valdiation tool. Any feedback or suggestions would be appreciated.

Technical Info:
This Xml validator is based on the DotNet XmlValidatingReader and is able to use either a client supplied schema or one specified in the Xml document. Although it is fairly fast, there will be a delay to load the schema from a slow web server and multiple schemas are only possible if you use the xsi:schemaLocation method to define the schema location.

Files for validation

Source xml data
Schema location The default namespace in the document is the location
The location is defined via xsi:schemaLocation
Use the file specified below

Remove duplicate errors
Simplify namespaces in errors
