Abstract (in Japanese) (See Japanese page) 
(in English) A method is proposed for translating queries in a subclass of XPath according to XML schema evolution based on the tree-embedding relation. A query translation is said to be correct if the result of every query to an XML document valid against the schema before evolution is equal to the result of the translated query to the XML document valid against the schema after evolution. Correctness of that the translation method is correct is proved.
