Actually, I've been trying to explain that I don't use them in creating
*reusable* components, but merely to fragment large works into manageable
pieces (manageable for me, not my tools).
Indeed, problems arise when trying to use them as reusable components
because they aren't designed richly enough to support that well.
When I've needed reusability I've done so at a semantic level, not a
syntactic level. That was the reference I made to needing to take one
lesson from another presentation to include in a given presentation ... I
refer to the lesson by ID and the other presentation by URI and my
*production* system (built with XSLT applying concepts of applicability and
effectivity) brings the two together ... not my authoring system or XML
processor.
As a result of personal experience trying to do so, I now don't counsel
external parsed entities be used as reusable fragments.
I hope this detail helps.
.......... Ken
