In confluence (wiki software from Atlassian) there is an “excerpt” feature that lets you do “transclusions”.

You mark one part of a page as “excerptable” and then from any other page you can “include” that “excerpt”.

It’s quite neat. Helps you have the same content reused and reordered in different ways.

... the ability to link to sections of a text ...

That sounds like #transclusions which is a fundamental principle of #Xanadu.

#Metawiki offers something similat, though it's not seamless / friction-free.
