Re: [Glossary] Definition of a portable document (and other things...)

Deborah, I like your definition, it is not only simpler but also uses
logical composition (that "any aggregate whose content is portable is
itself portable") . I don't like "display" but that's a fine point.

To try to make this yet even simpler, it's been said that "you can't take
it with you!". To me the essence of portability is that "you *can* take it
with you!".  And the "it" means the content that we are calling portable...
if what you can take with you (inc. cache and use later) is only a snapshot
of one particular state of that content then the content itself cannot
thereby be considered portable.
