The line it refers to is:
XSDElementDeclaration specialElementDeclaration = 
(XSDElementDeclaration)((XSDModelGroup)((XSDModelGroup)((XSDParticle)(xsdComplexTypeDefinition.getContentType())).getTerm()).getParticles().get(1).getTerm()).getParticles().get(j).getTerm();

Reproducible: Always

Steps to Reproduce:
1. Simply run the XSDGenerateHTML
Note: The other part, XSDMainExample runs fine

Marcelo,

I actually have no idea what this is supposed to produce.  When applied to Library.xsd, it doesn't appear to do anything useful.

I am afraid this is a legacy, long forgotten code. And I really don't think I've created it. Looking at the CVS history, I see it was located in a xsd.test bundle that, back in 2005, had examples instead of tests. I did wrote the HTML exporter example, though.

Ed, if you want I can try to figure out what is going on here although, as you know, the XSD code is not my strength. Actually, it is probably a "Ed-only strength" ;-)

That said, can "org.eclipse.emf.test.xml.xsd.XSDFeatureTypeTest" be used as an example of how to drive the XSD API? If it can, I would suggest dropping "org.eclipse.xsd.example", as it seems to be old and not really maintained. If it can't, I wouldn't mind writing such a test instead of spending time on XSDGenerateHTML as the test will be at least exercised during builds.
