Below is a little error from the build of the mqi package. The messages refer to sections of the main manual using \secref{} in Latex. Is there a way to refer to sections of the main documentation from a package?

One can see the problem also online, here:  
[https://www.swi-prolog.org/pldoc/doc\_for?object=section('packages/mqi.html')](https://www.swi-prolog.org/pldoc/doc_for?object=section(%27packages/mqi.html%27))

Scroll down to Section 1.3 and check the reference to top level/quickstart, it is not being translated to a link.

```prolog
[81%] Generating mqi.html
No label for ref "sec:pengine-references"
No label for ref "sec:quickstart"
No label for ref "sec:attvar"
No label for ref "sec:chr"

No label for ref "sec:threaddebug"
No label for ref "sec:attvar"
No label for ref "sec:attvar"
[81%] Built target mqi.doc.html

```

Note that the messages appear only under MSYS2, not under Linux (but the problem is the same, no link).

That won’t work easily because it concerns a different document ☹ Best work around is probably an explicit hyperlink to [https://www.swi-prolog.org](https://www.swi-prolog.org).
