Re: xml schema Second Edition-regarding substitution group

yes ,I found that it not a change (only when I declared it, I found that both has to be kept global, since it was not explicitly mentioned in the 1st Edition, I misunderstood it.)
 As u have mentioned, declaring it as choice will also not work, because I want  the elements to be substitutable This is to achieve  translation of equivalent property (to show two properties are semantically equal  ) from OWL to xml Schema.
So I have decided to keep the properties as global and apply substitution group . thereafter I can restrict only its occurence and not its type.
I think this is the only possibility.
thank u,

Your analysis is essentially correct, but this is not a change from
the first edition.

The best you can do is make the implicit choice explicit, and use
local declarations:
