[XeTeX] grouping multiple types of footnote per section on same page

[matthias reinert]

Hi Wilfried, hi don,

the desired ordering would be

page 1:
a s1 
b s1 
c s1
1 s1 .. 6 s1

a s2
1 s2 .. 4 s2//

page 2:
contd. 4 s2

b s2
c s2
d s2
5 s2

a s3
1 s3
2 s3

the idea of having 4 different types of footnotes seems to solve the
problem for section 1 (footnoteA, footnoteB) and section2 (footnoteC
footnoteD) on the first page, but I would run into trouble on the second
page: section 3 can't restart with footnoteA footnoteB which would be
wrongly placed above footnoteC and footnoteD:

page 2:
a s3 (fnA)
1 s3 (fnB)
2 s3

b s2 (fnC)
c s2
d s2
contd. 4 s2 (fnD)
5 s2

I like the proposal using endnotes in short sections (which pose the
problem of overlapping footnotes). It would keep readability, saves some
space and I'll test it.

thanks for Your replies and helpful commenting on,
