Hi,

This kind of a follow up to something I posted to XML-DEV /-//Validating 
against the correct root element using library schemas// 
/http://lists.xml.org/archives/xml-dev/200505/msg00263.html (BTW thanks, 
Michael and Henry, for getting back to me).

If I'm creating a set of library schemas where I want to enforce that 
particular document / message schemas are valid and that no fragments of 
documents are valid  it seems I have two approaches  -

1) I adopt a strict venetian blind approach i.e. there are no global 
element declarations in my library schemas and only a Russian doll 
approach in my message / document schemas to enforce that there is only 
one valid root element (however that way I can't create any reusable 
elements just reusable types).

2) I use xsd:group to hide my global elements but get reuse from them by 
referencing the groups.

I have a some questions -

Would the xsd:group approach just be a dirty hack?

Is there any reason why OASIS have not adopted xsd:group (sorry to keep 
banging on about OASIS but the New Zealand government are looking at a 
number of their standards ;-) )?

Cheers,

Fraser
