Include content of other page

[codewing]

Similar to creating a link to another page is it possible to include the content of another page?

something like

# Header

The concept works like this:

{{<xref:id_of_another_file>}}

And we build on top of that...

Why?

We write documentation of general concepts and would like to include these definitions/pages in other sites as well.
