This is a tricky one, but I think option C is the way to go. Gotta love those XML Schema redefine tricks!

I'm not sure, but I think D is also a possibility if the schema doesn't allow for such changes.

Wait, is 'testml.xsd' the same as '[testmixsd]' mentioned in the question? That could be a trick question!

Haha, option D is just a cop-out! Of course this can be done using XML Schema, we just need to figure out the right approach.

Option B looks promising, but I'm not sure about the 'substitutionGroup' attribute. Wouldn't it be better to use 'xs:redefine' instead?
