....axiom system is a property of the fragment as a whole. Solving containment itself is only a step toward optimization, but developing a framework for, and thorough study of, simplification in the context of XPath fragments remains an important open research issue. Closest in spirit to our paper is [19]. It presents a set of rewrite rules for eliminating upward modalities, which is similar to some of our results in Section 5. However, 19] focuses on a single large XPath fragment, and their results do not apply to the smaller fragments considered here. Normal forms for one simple fragment of ....

However, [19] focuses on a single large XPath fragment, and their results do not apply to the smaller fragments considered here. Normal forms for one simple fragment of XPath are examined in [26] for tree patterns, 1, 20] present algorithms for achieving minimization, which can be viewed as a certain normal ....

....natural and results in an easily understandable code. However, intertwining construct and query parts also has drawbacks: 1. Complex queries are often di#cult to express and to understand, 2. unnecessarily complex path selections, e.g. XPath expressions involving both forward and reverse axes [5], are possible, 3. in presence of several path selections, as in Example 1, the overall structure of the retrieved data items might be di#cult to grasp. Among the query and transformation languages, UnQL [6] is a noticeable exception. This language first considered using patterns instead of ....
