Hi Mark,

If you want to use XML Schema then the only way to get an "open" document (allows you to add elements and attributes not declared in the schema) is to use the wildcard facility (xs:any and
xs:anyAttribute). This means that you need to include these in the XML Schema but that's not necessarily that hard to do. You can for example create an abstract base type that is a wildcard type
and then derive all other types from this type which would create an "open" document.
If you don't mind trying a different schema language Schematron is open by default which means you can do these things by default.

Cheers,
/Eddie
