But note that general text entities *don't actually do point 3*. General
text entities *ARE NOT REUSABLE*. In fact, the only way to have re-usable
SGML documents, as James has pointed out, is to make them documents
syntactically (even if the objects may be semantically subparts of documents).
While external text entities are a useful convenience for single-person
authoring, they are not useful as a general mechanism for managing SGML
data as re-usable objects.
