Joseph, I do not think that the choice model you suggest, has so many benefits that a change of the current schema is justified: o You argue, that you can maintain a defined sequence of the certain types of children within KeyInfo. But this is only true, as long as there are used only the predefined types of XML-Signature. The sequence cannot be maintained any more if there are more than two newly defined types are used: <KeyInfo> <NewFoo1/> <NewFoo2/> <NewFoo1/> <NewFoo2/> <KeyInfo> This example is validating with your new schema proposal. o As Merlin argues, it would be sufficient to semantically restrict the number of occurences for KeyValue to a maximum of one; this would increase the number of possibilities for reuse of the KeyInfo type by other parties.
