The command is supposed to be a _single_ command per document without
any printed output in the Info.  Its purpose is so that the Info reader
is able to propose a corresponding web link (containing the same
content) for the current Info-internal page.

It may work through anchor and cross-manual reference, but then this
anchor would need to have some boilerplate text convention in order to
be clearly recognizable by the Info reader.

Having a dedicated macro produce this reference and the boilerplate text
would make sure that it's recognized.  However, Info manuals are not
English-only, so a fully visible standard English boilerplate text might
not be the best idea.

I don't.  How should I?

I'll enter that information in the respective bug report for
implementing the functionality in Emacs' info reader.

In the long run, however, I consider it desirable to embed that info in
the Info file itself rather than having to consult a centrally managed
database that is sure to be incomplete, requires work to keep up to
date, and will only cover software of public interest.
