This is followed by an outline of Schematron and the intended uses which have guided its design.
More formally, the nodes and arcs within a graph of data can be traversed to both identify nodes, and then make assertions about the relationships of those nodes to others within the same graph.
Assertions are therefore the mechanism for placing constraints on the relationships between nodes in a graph (elements and attributes in an XML document).
The majority of these have taken the basic premise of recasting DTD functionality in XML syntax with the addition, in some cases, of other features such as data typing, inheritance, etc [XMLSchema].
The use of XML syntax provides additional flexibility through leveraging existing tools for markup manipulation, while the 'value added' features satisfy the requirements of developers looking for closer integration with databases and object-oriented languages.
Tree patterns are the schema paradigm underpinning Schematron as a validation language.
