We prove that various containment and validity problems for tree pattern queries with respect to a schema are EXPTIME-complete. When one does not require the root of a tree pattern query to match the root of a tree, validity of a non-branching tree pattern query with respect to a Relax NG schema or W3C XML Schema is already EXPTIME-hard when the query does not branch and uses only child axes. T...

We attempt to unify the traditional markup notion of validation with the process of type assignment used by W3C Schema. We show how validation can be extended to provide typing information for a schema language, such as Relax NG, which doesn't have explicit type declarations.

conclusions the two treatment methods had similar effects and there were no significant difference between them, while significant improvement was seen in the experimental groups compared with the control group. background shortness of skeletal muscles may cause musculoskeletal disorders of body; improvement of these muscles may improve posture and body function. objectives the aim of this stud...

Abstract Despite the significant improvements that self-supervised representation learning has led to when from unlabeled data, no methods have been developed explain what influences learned representation. We address this need through our proposed approach, RELAX, which is first approach for attribution-based explanations of representations. Our can also model uncertainty in its explanations, ...

The extensible markup language XML has become indispensable in many areas, but a significant disadvantage is its size: tagging a set of data increases the space needed to store it, the bandwidth needed to transmit it, and the time needed to parse it. We present a new compression technique based on the document type, expressed as a Relax NG schema. Assuming the sender and receiver agree in advan...
