Warning

The template uses a sentinel value to detect whether it has been filled out properly when inserted via Template:Request edit button/preload. Using the sentinel value produces a warning message:

{{Text diff|ORIGINAL_WIKITEXT|CHANGED_WIKITEXT}}

Warning Unnamed parameter |1= set to default value. Please change it. Failure to use {{Text diff}} to specify your requested text changes, if not adequately described above, may lead to your request being denied.

Limitations

This template is suitable only for comparing a single in-line string of text. Use of this template to compare multi-line content (i.e. HTML block content, text including line breaks) will result in syntax errors.

This template must be placed on a new line, i.e. with a line break before the template. Adding the template to a line that is indented with a colon or asterisk may result in syntax errors.
