Hi. I think in some conditions,the TypeRef can be met when computing prime or quantifier of a type.For example: $a,/book/author If the context bind $a to a type(which is a typeRef):"type AUTHOR",and the path expression /book/author results type(which is a itemType):"element author {...}",how about the expression sequence wrote before if we want to compute the prime() of that exprSeq? One way may solute this problem I think,is to expand the TypeRef before computing prime(). But here comes anthor question:if the TypeRef is defined recursively,what should we do? Thank you for your time and consideration,I'm waiting any comments.
