Right -- so my point would be, _this_ case at least is not a
corner-case wrt xs:redefine as such, but rather an issue for
namespace/schema/cache management in multiple-validation-session
contexts. Many/most of the relevant issues might arise without
redefine being involved at all, e.g. if I have two documents which
share a namespace but have xsi:schema-location hints pointing to
differing schemas (e.g. different versions) for that namespace.
