oh no, i don't think i can hack them. what i'm more concerned about is:
does a footnote that, is changed to an endnote change in content and
meaning?

please do. as long as we're talking about practices that involve content,
and not presentational stylings.

how's about object, for instance?

in which case shouldn't you attempt to provide that content in an 
alternative
way? longdesc in the case of images springs to mind.

"sorry bob, i know you wanted to come to our wedding, but our invitations
were printed in exquisitely filigrane typography on the finest of 
papers...but as
you're blind, we thought you wouldn't appreciate the beauty of the 
invitation, so
we just left you out when compiling the guest list"

again...yes, great, the presentation *is* part of the content. does 
that, however,
mean that you should not strive - if all else fails - to provide an 
alternative?

which is useless to me if i can't access it in the first place...

because if it's not text - and i still maintain that, regardless of how 
much text is
inside the pdf, if i can't access it, it may as well not be there - then 
an alternative
needs to be available.
