ODD allows an attList with `@org="choice"` with `@mode="delete"` attributes #2533

An <attList org="choice"> allows the definition of multiple attributes which are deemed to be in alternation -- only one can be selected. However, you can then put @mode="delete" on any of those attributes, giving rise to a situation which makes no sense at all as far as we (@sydb, @HelenaSabel and myself) can see. Schematron should prevent this.

At the VF2F we're having some trouble figuring out what to do here.

My own view is that attList/@org and attDef/@mode are about two different operations. @mode indicates how to apply the customization (ie: remove this attribute). @org indicates how the resulting compiled ODD should be transformed into RelaxNG.

So the value of @org is inconsequential to the processor's operation here.

On the other hand — and perhaps this is a different ticket — it is unclear how @org should be treated with @mode="change" on the parent. Should it result in switching the value of attList/@org on the resulting spec?
