Register directionalityFinder specified by class with XXE. A directionalityFinder is some code used by the "Bidi Support" add-on to determine the directionality —left-to-right or right-to-left— of any XML element.

Child elements of directionalityFinder:

class

Register directionalityFinder implemented in the Java™ language by class class (which itself implements interface com.xmlmind.xmledit.edit.DirectionalityFinder).

property

Property child elements may be used to parametrize a newly created directionalityFinder. See bean properties.

A directionalityFinder element having no class child element may be used to discard registered directionalityFinder.

XHTML configuration: the directionality of an XML element is determined by following a complex set of rules involving the dir attribute and the bdi and bdo specialized elements. These rules are specified in the HTML specification.

<directionalityFinder>
  <class>com.xmlmind.xmledit.edit.HTMLDirectionalityFinder</class>
</directionalityFinder>

DITA and DocBook configurations: the directionality of an XML element is determined by examining the value of its (possibly inherited) dir attribute.

<directionalityFinder>
  <class>com.xmlmind.xmledit.edit.HTMLDirectionalityFinder</class>
  <property name="options" type="String" value="dir ltr rtl lro rlo" />
</directionalityFinder>

TEI Lite configuration: the only way to determine the directionality of an XML element is determined by examining the value of its (possibly inherited) xml:lang attribute. For example, attribute xml:lang="ar-EG" —Arabic, Egypt— implies that the directionality of an element is right-to-left.

<directionalityFinder>
  <class>com.xmlmind.xmledit.edit.HTMLDirectionalityFinder</class>
  <property name="options" type="String" value="xml:lang" />
