Here follows my minimal example. I reasoned that the identifier [topica] might act as a label, or an anchor, or whatever the correct ConTeXt name is, for a reference.
---------------------------------------------------------------------------

\definedelimitedtext[topica]
\setupdelimitedtext[topica][left=,right=] %maybe superfluous? I do not need a layout different from the rest of the text.
\starttext

Some text.

\starttopica
Some text to explain a certain topic, called topica.
\stoptopica

Some more text about topica. (See discussion on \at{page}[topica])

\stoptext

---------------------------------------------------------------------------
To avoid any misunderstanding: this is no longer a problem since I have been given excellent advice. But it intrigues me. Why can some identifiers, for example of figures, be used for internal references and others not?

Best regards,
