Never say 'never' :-) I agree with all of Eddie's reply, except for the last bit: Eddie Robertsson <erobertsson@allette.com.au> writes: > Since a derivation by extension always creates the new type by > "sequencing" together the content in the base type with the content > in the derived type you can *never* use <xs:all> as part of an > extension. If the base type def'n was empty and the extension was all and only a valid <all>, I think the sequence is waived and the result would be OK. ht -- Henry S.
