I think because I am creating a circular reference, as I have allowed an option element to contain an options element which must contain an option element in the XDS below, I am getting a
'os-nonambig: WC[##any] and "http://
....":options (or lements from their substitution groups) violate "Unique Particle Attribution". During validation against this schema, ambiguity would be created for those two particles.'
error when validating using SAX (Java) / apache xerces. I have experimented with using another namespace "ab" as you can see below, but this hasn't worked, I get the same error. I want the ability for an option to contain options, how would I go about this?
