What does the VAR phrase element indicate?

The VAR phrase element is used to indicate an instance of a variable or program argument in the context of accessibility and structured documents. This element helps to differentiate these types of text from standard text, making it clear to users, especially those employing assistive technologies, that the information represents a variable or programming concept, which may require different handling or understanding than regular text. Identifying variables within documentation is crucial for both clarity and comprehension, especially in technical documents where such terms play a fundamental role in programming and technical communication.

This context of programming terminology ensures that users who rely on screen readers or other assistive technologies receive appropriate cues about the nature of the information being communicated. It delineates the content that requires special consideration, thus enhancing the accessibility of the document.
