- In considering R. Raisch's link types, it seems to me that the
- expansion and replacement can be combined and generalized. In both
- cases portion of the document is replaced. In expansion case, the
- condensed text is replaced (perhaps temporarily) with the enlarged
- text, in replacement the entire document is replaced with some other.
- So the more general case is a link which labels a range in both the
- source and target document. The replacement link labels the entire
- document, the expansion labels only a portion.

- As for execution links in general, I see Dan's point that adding
- procedures to documents makes them difficult to manipulate. And N
- Borenstein has pointed out (in Mime) the dangers of executing
- arbitrary code. But I still see that there are functions which only
- code can provide, and so we just face the challenge of designing a
- language that is both powerful and safe, perhaps sacrificing Turing
- completeness. Is Atomicmail [tm?] such a language?
