As Adrian mentioned, you can create an XML instance and validate that with LIBXML, this will show non-deterministic content models from DTDs. For example on: test.dtd ========= <?xml version="1.0" encoding="UTF-8"?> <!ELEMENT test (a*, b*, a*)* > <!ELEMENT a (#PCDATA) > <!ELEMENT b (#PCDATA) > <!ELEMENT c (#PCDATA) > test.xml ======== <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE test SYSTEM "test.dtd"> <test> </test> LIBXML will give System ID: .../test.xml Main validation file: .../test.xml Schema: .../test.dtd Engine name: LIBXML Severity: error Description: validity error : Content model of test is not determinist: (a* , b* , a*)* See also http://www.w3.org/TR/REC-xml/#determinism and Tim Bray notes in the annotated XML specification: http://www.xml.com/axml/notes/Determinism.html Best Regards, George -- George Cristian Bina <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com On 07/10/14 18:09, Oxygen XML Editor Support (Adrian Buza) wrote:
Hello Frank,
On what platform are you running Oxygen (Windows, Mac, Linux)? Oxygen uses Xerces for XML parsing and validation against DTD. For DTD validation there is just the default mode, there is no "strict mode". The options that affect DTD validation in Oxygen are located in Options
Preferences, XML > XML Parser
Are you validating the DTD itself or an XML against the DTD? If you validate the XML against the DTD, you can also use LIBXML (xmllint). In Windows you can also use MSXML 4.0 or MSXML.NET. You can find these in the the 'Custom Validation Engines' toolbar.

Hello!
First time poster. I hope this question hasn’t been up for discussion before – I was not able to find anything helpful in the archives. I have a DTD that I need to debug. The ”problem" is that Oxygen validates the DTD just fine, whereas some XML editors (e.g. XMetal) complain about a ”non-deteministic” content model. So, my question is, does Oxygen (15.2) has some kind of ”strict mode” DTD validation? Because I do not have access to some XMetal-debug-fo, I must use Oxygen to debug my DTD.
Any help is greatly appreciated!
