Subject: footnotes when using RtL (Arabic)

Dear all,

Two quick questions regarding footnotes and Arabic:

1. How do I get a footnote rule/marker to go from right-to-left (i.e. to begin at the right margin instead of the left margin)?

2. I would like some of my footnote streams to run RtL for Arabic, and also for those footnotes to be in paragraph form (i.e. \setupnote[afootnote][paragraph=yes] ). But when I add this command, my footnote instead runs LtR, the letters get cut up (i.e. the Arabic script is not connected), and I lose my footnote marker to add insult to injury. How should I define a footnote stream to run RtL in paragraph form?

Many thanks in advance.

Kind regards,
Talal

p.s. Below is my attempt thus far, with the problem of defining paragraph=yes, and with the problem of the footnote rule/marker. Reference to what I should change in this example would be most helpful:

==========================

%%%	SETUP AREA

%%	PAGE SETUP
\setuppapersize[A4][A4]
\setuplayout[grid=on]
\showgrid
\setupinterlinespace[line=3.8ex]
\setupindenting[yes,big]

%%	FONTS
\usemodule[simplefonts]
\setupsimplefonts[size=12pt]
\definefontfeature[default]  [default]  [mode=node,script=arabic]
\setmainfontfallback[Lotus Linotype]  [scale=1.33,features=arabic,range={arabic,arabicsupplement}]

%%	PARAGRAPH DIRECTION & SPACING - ARABIC - ENGLISH
\def\arabpar	{\textdir TRT\pardir TRT}
\automigrateinserts % to ensure that certain levels of footnotes show up (raw MKIV feature)

%%	FOOTNOTES
\setupfootnotedefinition[location=serried]

\definenote[afootnote][conversion=set 2]
\setupnote[afootnote][paragraph=yes]

%%%	TEXT
\starttext

\input knuth

\startbaselinecorrection\setupinterlinespace[line=5ex]
\arabpar{

}
\stopbaselinecorrection

Thus, I came to the conclusion that the designer\footnote{Such as Knuth himself.} of a new system must not only be the implementer and first large--scale user; the designer should also write the first user manual.

The separation of any of these four components would have hurt TEX significantly.
