* CDATA section so the file becomes well-formed. Non-script elements are left
* untouched.
*
* Assumptions / limitations:
* - Script elements are treated as leaf nodes (no child elements expected).
* Nested XML tags inside a script block are not supported and the regex
* will not handle them correctly.
* - The detection of an already-present CDATA section relies on the opening
* tag being immediately followed by '<![CDATA[' (with optional whitespace).
* If a script block mixes text and CDATA it is left unchanged.
*
* This is applied to raw XML submitted through the editor's "Raw XML" path
* before the validation step, giving a best-effort fix rather than a hard
* rejection for the most common authoring mistake.
