Escape <, &, > in text as < etc., or wrap literal blocks in CDATA:
<![CDATA[ if (a < b) { ... } ]]>
Going deeper
In production XML work, Text and CDATA matters when documents, stylesheets, or apps must stay maintainable across teams and releases—not only in isolated demos.
Common pitfalls
Watch for copy-paste configs, skipping validation or tests, and mixing concerns (structure vs presentation vs behavior) in one layer.
Practice
- Apply one technique from this lesson in the playground.
- Write one interview-style sentence explaining when you would use text and cdata on a real project.
