Oxygen XML Forum

I have the following xml document:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE Attesten SYSTEM "SchadeAttest.dtd">
<Attesten xmlns='http://www.datassur.com/'>
<Attest>
....
</Attest>
</Attesten>

but when I try to validate it, I get the following error:
[Message:E Attribute "xmlns" must be declared for element type "Attesten". SystemID:null, Line:3, Column:1]

Can you explain this?

Sincerely,
Patrick muls

Hi,

DTDs are not namespace aware, therefore xmlns is seen as any other attribute and it has to be specified in the DTD in the attribute list of the element that contains it.

You should have in your DTD something like Best Regards,

George,

Thanks for the explanation. I couldn't find any reason browsing in Wrox's Professional XML. I probably looked in the wrong place. Now the document is validating OK.
