We were discussing if the use of substitution groups would increase the range of use of xsi:type, by range of use meaning the range of types available for an xsi:type to declare itself as. The source of our confusion stems from xsi:type being based on the substitutability of types the same as substitution groups are. Thus the question is if extensive use of substitution groups in a set of schemas creates a greater number of substitutable types for xsi:type to draw upon for its nefarious purposes :) I suppose at that level it is really a question of schema design and community experience, does reliance on substitution groups extend the range of substitutable types. Anyway we concluded tenuously that there was not a definite reason for it to increase the number of types. The question was raised because I was certain I had seen an article somewhere arguing this point, but I can't find it via google currently.
