        "Digester" component of the Jakarta Commons Subproject
        DTD for the definition of Digester rules in XML.
        $Id: digester-rules.dtd 471661 2006-11-06 08:09:25Z skitching $

        Applications wishing to reference this DTD in their own documents
        should use the following DOCTYPE declaration:

        <!DOCTYPE digester-rules PUBLIC
         "-//Jakarta Apache //DTD digester-rules XML V1.0//EN"


<!-- This document type defines an XML format for defining Digester rules.
     Digester is a framework for pattern-matching-based parsing of XML into
     Java objects. See  -->

<!ENTITY % rule-elements "bean-property-setter-rule | call-method-rule |
                   call-param-rule | object-param-rule | node-create-rule |
                   factory-create-rule | object-create-rule |
                   set-properties-rule | set-nested-properties-rule |
                   set-property-rule | set-top-rule |
                   set-next-rule | set-root-rule" >

<!-- digester-rules is the root element. -->
<!ELEMENT digester-rules (pattern | include | %rule-elements; )*>

<!-- <pattern> defines a matching pattern, or part of a matching pattern. Any
     rule nested in a pattern element prepends its parent's to its pattern.
     Patterns may be recursively nested.
       <pattern value="foo">
          <pattern value="bar">
            <object-create-rule pattern="baz" classname="Fubar" />

     The above sample fragment defines an ObjectCreateRule associated
     with the pattern "foo/bar/baz".

  Note that the use of pattern elements is optional; an alternative is for
  each rule element to contain a 'pattern' attribute.   -->
<!ELEMENT pattern (pattern | include | %rule-elements; )*>
<!ATTLIST pattern
    value CDATA #REQUIRED>

  <include> allows one set of digester rules to be included inside
  another. The 'path' attribute contains the URI of the document to
  include. Inclusion behaves as if the included rules document is
  'macro-expanded' within the outer document.
  Programmatically initialized rules can be included as well, via the
  'class' attribute. The 'class' attribute should contain the name
  of a class that implements
<!ELEMENT include EMPTY>
<!ATTLIST include
    path  CDATA #IMPLIED
    class CDATA #IMPLIED>

<!-- Each 'rule' element below corresponds to a concrete subclass
     of org.apache.framework.digester.Rule.
     Each 'rule' element has an optional 'pattern' attribute, which
     defines the pattern for that rule instance. If the rule element
     is nested inside one or more <pattern> elements, those patterns
     will be prepended to the pattern specified in the rule's 'pattern'
     attribute. -->

        - select an object from the current digester stack to pass as a
          parameter value. If this is defined then from-stack is implicitly
          true. If from-stack is defined but this is not defined then this
          has an implicit value of zero, ie the top object on the stack is
          passed as the parameter.

        - Optional. This attribute is not normally specified. If it is provided,
          then this rule is executed *only* if the matched element has an attribute
          with this name.
        - The type of the object to be passed to the target method.
        - Initial value for the object. The BeanUtils converter module will
          be used to convert this to the type specified by the type attribute.
          Optional; if no value is provided then the converter will be invoked
          to convert NULL to the target type. For most (but not all) converters, 
          NULL input results in NULL output.
