Yes, specialized elements and attributes in DITA can be used in combination with each other to create highly tailored and domain-specific content structures. The flexibility of DITA allows content creators to utilize specialized elements and attributes in a modular and customizable manner. This means that within a DITA document, you can employ multiple specialized elements and attributes to represent the content effectively.

Using specialized elements and attributes in combination allows content creators to capture complex domain-specific information. Elements can encapsulate different content types, while attributes provide additional context and details. The combination of specialized components enables content creators to address a wide range of content requirements within a specific domain or subject area.

Example:

In a specialized DITA document for scientific research, content creators can use specialized elements like <experiment> to represent experiments and <result> to present experimental results. Additionally, they can apply attributes such as @experiment-date to specify the date of the experiment and @experiment-location to indicate where the experiment took place. This combination of elements and attributes allows for comprehensive and domain-specific representation of scientific research data.
