Re: [xml-dev] Access to elements from schema imported once removed !

["Fraser Goffin" <goffinf@hotmail.com>]

The early concensus appears to be '.. its an XML Spy thing'. I am on

verify that other validating parsers can successfully consume the document 
as others have already kindly done (thanks). I will report back what I find.
