Example: Correct the constraint for the machinery task

This section is non-normative.

For DITA 1.3, the OASIS DITA TC failed to update the constraint for the machinery task. In this scenario, an information architect corrects that oversight; she makes the (new for DITA 1.3) <tasktroubleshooting> element available in the body of the machinery task.

Example

This section is non-normative.

Note (non-normative):
This example assumes that the information architect has already implemented her own document-type shell for the machinery task information type.
  1. She makes a copy of the machineryTaskbodyConstraint.mod file and renames it correctedMachineryTaskbodyConstraint.mod.
  2. She modifies the correctedMachineryTaskbodyConstraint.mod file to declare the entity for the <tasktroubleshooting> element and make it available at the correct place within the task body. (Her modifications are highlighted in bold below.)
    <!ENTITY taskbody-constraints
      "(topic task+taskreq-d machineryTaskbody-c)"
    >
    <!ENTITY % prelreqs                                        "prelreqs">
    <!ENTITY % context                                         "context">
    <!ENTITY % section                                         "section">
    <!ENTITY % steps                                           "steps">
    <!ENTITY % steps-unordered                                 "steps-unordered">
    <!ENTITY % steps-informal                                  "steps-informal">
    <!ENTITY % result                                          "result">
    <!ENTITY % tasktroubleshooting                             "tasktroubleshooting">
    <!ENTITY % example                                         "example">
    <!ENTITY % closereqs                                       "closereqs">
    
    
    <!ENTITY % taskbody.content
                  "((%prelreqs; |
                     %context; |
                     %section;)*,
                    (%steps; |
                     %steps-unordered; |
                     %steps-informal;)?,
                    (%result;)?,
                    (%tasktroubleshooting;)?,
                    (%example;)*,
                    (%closereqs;)?)"
  3. She updates her company-specific document-type shell to integrate the updated constraint.
  4. After updating the catalog.xml file to include the new constraints file, her work is done.
