KB User's Guide - Documents Tab - Embedding user specific content in KB documents (HTML editor only)
This feature allows authors to embed, in one document, content meant for specific individual users. When the activated document is rendered by a particular user, all content marked for other users is filtered out.
To mark content so that it is visible for only specific users, use span tags with a class attribute of "visible-only-to-user_qualified@domain".
For example, to embed content meant for user email@example.com only:
<span class="firstname.lastname@example.org"> Some info for John Smith's eyes only here.</span>
In the same document, to embed content meant for user email@example.com only:
<span class="firstname.lastname@example.org"> Some info for Jane Doe's eyes only here. </span>
