We present a prototype that implements a set of logical rules to prove the satis ability for a class of speci cations on XML documents. Speci cations are given by means of constraints built on Boolean XPath patterns. The main goal of this tool is to test if a given speci cation is satis able or not, showing the history of the execution. It can also be used to test if a given document is a model of a given speci cation and, as a subproduct, it allows to look for all the relations (monomorphisms) between two patterns or the result of doing some operations by combining patterns in di erent ways. The results of these operations are visually shown and therefore the tool makes these operations more understandable. The implementation of the algorithm has been written in Prolog but the prototype has a Java interface for an easy and friendly use.
