Oxygen returning errors on Validation with no DTD or Schema

[alphie]

Hi,
I seem to be running into an unusual and frustrating problem when creating new xml documents. Normally when creating an xml document, I'm prompted by Oxygen to select a DTD or schema by selecting the checkbox or not. When I deselect the DTD/Schema checkbox and start writing an xml doc, Oxygen gives me all these errors telling me that various elements must be declared as I create elements. It didn't used to do this before I upgraded so I'm a little confused as to what's happening.
If I haven't selected that a document should validate against a dtd or schema, why is it doing that? I must be missing something simple.
Thanks for any help in advance.

Hello,

By default if there is no schema declaration and no schema association Oxygen should only check for XML well-formed.

However, Oxygen has a large number of Document Type Associations which replace and expand the Schema Associations from older versions of Oxygen. These associations can sometimes accidentally match a document with no schema or namespace so Oxygen ends up validating with a DTD/schema even though that's not what you intended.
e.g. a document with the root 'article' is detected to be of the type DocBook4 and as a result is validated with the DocBook 4 DTD.

You can check what Document Type has been detected for your file in the Properties view(Perspective -> Show View -> Properties), look at the 'Document type' label.

To disable the association for a specific document type you can go to Options -> Preferences -> Document Type Association and uncheck the one that's troubling you.

Let me know if this resolved the problem.

Regards,
Adrian
