is it possible to have partial topic access?

The basic building block of a FOSwiki web is the topic, and topics are made up of sections, subsections, paragraphs,... is it possible to limit (for example) the "view" of a paragraph to a certain group while leaving the rest of the topic visible? What about a section? Otherwise stated, is it possible to have a conditional rendering (editing, etc) of some part of a topic depending on the group?

thanks in advance, P.P.

The smallest unit subject to access control in Foswiki is the topic. If you need to protect or hide pieces of a topic, they can be placed into a separate "restricted" topic and then included into the public topic. The warn="" parameter of the INCLUDE macro can be used to tell the user if the include failed, or silently fail. For example, for this Question, a restricted topic might be Question826Restricted and then in the topic:

%INCLUDE{"Question826Restricted" warn="<span class=\"foswikiAlert\">Not available</span>"}%

Not available

In this case the topic does not exist, but if it was not accessible, it would generate the same message.
