Document element

Element schema Document element, Root of a schematron file

Attribute schemaVersion An optional attribute, containing a non-empty string indicating the version of the Schematron schema in use

Attribute defaultPhase An optional attribute, containing an IDREF which links to a phase definition

Attribute queryBinding An optional attribute, containing a non-empty string indicating the query language binding in use. Could be xslt1, xslt2 or python. Should match the implementation being used.

Data type, a non empty string 1

Element active A child of the phase element, the active element specifyies which patterns are to be used in this phase of validation.

Element assert An assertion made within the context (of the input document) specified by test attribute. If the test evaluates positive the assertion succeeds. If the assertion fails, the contained text is output.

Element diagnostic An individual diagnostic message referenced from an assert or report statements.

Element diagnostics A wrapper for individual diagnostic messages referenced from assert or report statements.

Element dir Text in which the writing direction is specified, either as ltr (left to right) or rtl(right to left) ltr rtl

Element let Declares a named variable. If within a rule, it is scoped to the current rule, otherwise it is scoped to the instance document root. The variable name is specified using the name attribute and the value calculated using the value attribute.

Element name Provides indirect access to nodes in the input document. If the optional path attribute is used, then this node is retrieved. Without the path attribute, the name of the current context node is retrieved.

Element ns Use this to specify a namespace and the associated namespace prefix. e.g. <ns prefix='dp' uri='http://www.dpawson.co.uk/ns#'/>

Element p A basic paragraph to help with documentation. Styling can be aided with the class attribute and the icon attribute. It may contain foreign elements.

Element param An element holding the name and value of a parameter passed to an abstract pattern.

Element pattern. A wrapper element for rules. A pattern is said to be abstract when the abstract attribute has the value 'true'. An abstract rule may be applied within different contexts with parameters being used to set the values retrieved in the pattern by the $name construction. Patterns may be documented using the title and p children. true false false

Element phase A set of patterns which are run at the same time. Enables progressive validation of an instance. The patterns are identified by the child active children, and the group of patterns (the phase) is identified by the id attribute on the phase element.

Element report If the test attribute evaluates positive, then the report is said to succeed. The output of a report statement is seen when the report succeeds. Additional diagnostic information may be generated by diagnostics element specified by the diagnostics attribute, an IDREF link. The mixed content of the element can include name, value-of, emphasis, dir and span elements.

Element rule A wrapper for a list of assert and report statements. The context in which the assertions are made is defined by the context attribute. true false

Element span An inline markup for decoration in the report message. The differentiation is set by the class attribute, used as in HTML

Element title A decorative element, allowing the association of a descriptive title to either an entire schema or pattern. Not required to be implemented.

Element value-of A way of retrieving values from the instance document. Context is the current rule context.

Element include Include an external Schematron file (as specified by the href attribute) appropriate to the place within the schema at which the include is found.

Rich. A set of optional attributes which may be used to decorate some elements preserve default

linkable attribute Optional attributes (role and subject). If the subject is present, the role attribute labels the arc between the context node and any nodes which match the subject value (an xpath expression).

Datatype uriValue A URI, used as the value of an attribute to specify, for example, an inclusion, an icon file, or simply a namespace URI

Datatype pathValue An xpath expression returning a node value or name (dependent on context)

Datatype exprValue An xpath expression returning a boolean value. See assert and report which both use the test attribute.

Datatype fpiValue A formal public identifier for containing element (schema, assert, report etc)

Datatype langValue The value assigned to an xml:lang attribute. Normally used to identify the language used in the containing element and its children.

Datatype roleValue The role attribute allows you to label the subject and subject nodes of assertions with simple labels. You could also see it as labelling the arcs between context subject and the arc subjects. For example, if generating RDF: see xml-dev archive For example, imagine you had a document containing gene sequences. You could use the role attribute to label the junk DNA parts. So the role could be what role the subject plays in the document, but is could be what role the subject plays in the pattern, or what role the rule plays in the pattern. The role attribute is used, therefore, like a kind of type binding, but instead of binding the node to a type name, it is bound to (one or more) arbitrary names.

Datatype flagValue A string used as the name of a boolean flag

Datatype nameValue The string which is the name of a variable, namespace prefix or parameter

Datatype classValue A string used to hold the class of an element

Element 'foreign' An element not in the Schematron namespace

Element 'foreign-element' Any element not in the Schematron namespace

An empty element with foreign attributes An element not in the Schematron namespace which is empty and may contain attributes

Foreign attributes attributes of elements in a namespace other than the Schematron namespace.
