I don't know about the this: scheme, but there is certainly a need for a
way to specify part of a document other than predefined #blargs. The
transclusion scheme in Ted Nelson's Xanadu project is a major example. The
idea is to support quoting from copyrighted materials by reference rather
than by copying. The project is working on ways to simulate the Xanadu
publishing model within HTML, and has suggested several ways to do
transclusions in HTML.
