When updating an XML schema, it is desirable that the new schema preserve the expressive power of the old one. The query preservation of an XML transformation between the old and new schemas is one of the formalizations of expressive power preservation. It means that, given a query to the old schema, there is some new query such that the answer to the given query for any old document coincides with the answer to the new query for the new document obtained by the transformation. This paper shows that a variant of the query preservation is decidable when transformations and queries are given by deterministic linear top-down tree transducers with regular look-ahead. |
