DTD validation

Post by scottbdr » Thu Jan 19, 2012 3:41 am

Is a document type association required to do DTD validation? I have my XML catalog set up to resolve a DTD system id and it does resolve to the correct path according to the catalog logging, and I still get a "No Schema associated with this document..." message when trying to validate.

Also having difficulties with xml:base in catalog resolution... is this supported in Oxygen?

Thanks, Scott

In case anyone else encounters something similar, this turned out to be a bug in Oxygen that prevented the validation and content completion from working if the system ID from the DOCTYPE declaration did not contain the ".dtd" suffix. e.g. <!DOCTYPE foo SYSTEM "bar">

This problem has been resolved in the latest maintenance build of Oxygen 13.2, 2012052412 (released May 28th).

You can download it from our web site:
