XSD - Validator problem

["Sebastian Hinterwälder"<sebi-hinterwaelder@gmx.de>]

Hi,

I have a problem and hope someone might help me. In my work with Extensible Textual Format I wanted to use an schema file that I found within an IBM project. I used "XML-Spy" to validate the schema and everytime it throws an error in the first line of code. I really don't see any error there. Maybe somone of you knows it. Therefore I posted the first lines of code above. Is there maybe a difference in the specification of schema that different validators use? 


Thanks for help,  Sebastian
