Conditional processing in DITA XML plays a crucial role in tailoring equipment documentation for different vessel types and equipment models. It allows content creators to provide variations of information within a single document, ensuring that readers receive the most relevant details based on their specific needs. This capability is invaluable in industries such as maritime, where vessels and equipment models can vary significantly.

Tailoring Content for Vessel Types

Conditional processing enables the creation of content branches that are conditionally included or excluded based on specific criteria. For example, in equipment documentation for ships, you can have separate sections for cargo vessels and passenger vessels. When a user accesses the documentation, the system can detect the type of vessel they are inquiring about and display the relevant section while hiding the irrelevant one. This ensures that users get information tailored to their specific vessel type, improving their experience and the effectiveness of the documentation.

Customizing Information for Equipment Models

Additionally, conditional processing allows for customization based on equipment models. For instance, a maritime equipment manual may cover multiple versions of a particular engine model. With conditional processing, you can create conditional branches for each model, providing instructions and specifications that are specific to that particular version. This ensures that users receive accurate and model-specific information, reducing the risk of errors and improving equipment maintenance and operation.

Example:

Here’s an example of how conditional processing can be used to tailor equipment documentation for different vessel types and equipment models:

<topic id="engine_maintenance">
  <title>Maintenance Procedures</title>
  <content>
    <condition audience="cargo_vessel">
      <p>For cargo vessels, follow these maintenance procedures: ...</p>
    </condition>
    <condition audience="passenger_vessel">
      <p>For passenger vessels, follow these maintenance procedures: ...</p>
    </condition>
    <condition audience="engine_model_A">
      <p>For Engine Model A, use the following maintenance instructions: ...</p>
    </condition>
    <condition audience="engine_model_B">
      <p>For Engine Model B, use the following maintenance instructions: ...</p>
    </condition>
  </content>
</topic>

In this example, conditional processing is used to provide tailored maintenance instructions based on the vessel type (cargo or passenger) and the equipment model (Engine Model A or B). Users will only see the information relevant to their specific context, enhancing the usability and effectiveness of the documentation.
