Abstract
In previous papers we presented a type system for a substantial fragment of the Web query language Xcerpt. It is a descriptive type system: the typing of a program is an approximation of its semantics. The type system was expressed by means of rules, which could be seen as a comprehensible abstraction of a typing algorithm. That system treats some query terms in a rather simplistic way. As a result the approximations produced for them are rather imprecise. In this paper we provide an improved type system, producing more precise results.
