{{RTFlink/doc}} is used to highlight that a link points to a rtf file. This may help the user to choose in advance what action is to be taken on the link itself as RTF files may take time to download and display on some systems, and their use on many websites is not compliant with the Web Content Accessibility Guidelines.

The following lines:

[http://www.example.org/Link.rtf Link] {{RTFlink}}
{{RTFlink|[http://www.example.org/Link.rtf Link]}}
{{RTFlink|[http://www.example.org/Link.rtf Link]|32 KB}}
