Ie for the schema to be included ( myNoNamespaceSchema.xsd ) I have: <schema xmlns:my="http://myNS" xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"> ... <xsd:element name="Book" type="my:CardCatalogueEntry"/> And the including schema has <schema xmlns:my="http://myOTHERNS" xmlns:xsd="http://www.w3.org/2000/10/XMLSchema" targetNamespace="http://www.library.org"> <include schemaLocation="myNoNamespaceSchema.xsd" /> ....nesting <xsd:element ref="book"/> ... end nesting Is the type of book in the namespace "http://myNS" or "http://myOTHERNS" ? I suspect that the scope of the xmlns:my declaration is brought across with the include and so the answer is "http://myNS". Also, consider the wildcard <any namespace="##other"/>. If the original ( myNoNamespaceSchema.xsd ) has no target Namespace then this <any> means "all qualified element information items allowed". But when I include it, does the meaning change to "all element information items other than 'http://www.library.org' "? thanks, mick.
