Yes, authors can create custom DITA specializations within their content to meet their specific documentation needs. Here’s how it can be achieved:

Define Specialized Elements: Authors can introduce custom elements that are not part of the standard DITA vocabulary. These custom elements should be documented and follow a consistent naming convention to ensure clarity and consistency in their usage.

Utilize Attributes: Authors can also create custom attributes for specialized elements. These attributes can be used to provide additional metadata or information specific to the organization’s content requirements.

Document Specializations: It’s essential to document these custom specializations in a separate document or schema. This documentation should specify the purpose of each element, its intended use, any associated attributes, and guidelines for authors on how to use them effectively.

Train Authors: Authors should be trained on the custom specializations to ensure they understand how to use them correctly. Training may include examples, best practices, and demonstrations of how to integrate specialized elements and attributes into their content effectively.

Example:

Suppose an organization wants to create a custom DITA specialization for marking content as “important.” They might define a custom element <custom-important> with an attribute <level> to indicate the level of importance. Here’s how authors can use this custom specialization:

<!-- Using a custom DITA specialization for marking content as important -->
<custom-important level="high">This is highly important content.</custom-important>
<custom-important level="medium">This is moderately important content.</custom-important>
<custom-important level="low">This is less important content.</custom-important>
