Thank you Hans for your answer. You don't need to change anything in
"supp-pdf.tex", because it works fine as is.
In fact I had messed up my Context installation, which normaly resides under
my "localtexmf\tex\context", but I had forgotten some old files from a
previous installation under "texmf\tex\context\base". After removing the old
context files from "texmf\..." the problem is solved.
I'm sorry for this.

I do use pdftex as my default tex-engine. The reason for creating other
formats was that I was experimenting to use Omega+Context, where I
encountered this problem, and so tried the same using TeX and eTeX.
Appropos Omega:
--------------
I have already tried the Omega specific commands (direction switching
commands and OTP's) in some small Context documents and the results are very
good: I used the Omega commands "\pagedir TRT" etc. for right-to-left, as
well as a chain of OTP's for mapping from ISIRI (8-bit standard for Persian)
to Unicode, context analysis, etc., for some Persian text. I was very
impressed by the results!
Unfortunately I know too little about Context/TeX to be able to set up by my
own a clean language environment for Farsi (and other right-to-left scripts
like Arabic and Hebrew) using these features. However if somebody starts
that, I would be very happy to contribute my part (at least to the language
specific issues).
Regards,
Behnam

I can look into that if I have the resources (fonts and so). One thing to
sort out [i did some experiments with etex] is to get color things and so
right, due to special swapping. No big deal, once i know the problems at
hand.
Where can I find the (really) latest omega specs? [since i also want to
look into the tex->xml part]

I think this might be a good starter, though it isn't that up to date.

The latest version is available at:
ftp://ftp.cse.unsw.edu.au/users/plaice/Omega
The TeX ==> XML/MathML primitives are excellent. It might become a
choice of TeX users for generating other markup forms.
It simply pipes out ASCII XML/MathML instead of a dvi in MMLmode!

I have uploaded an example for utf-8 encoded Persian text to be used
with Context+Omega to http://meineseite.i-one.at/behnam-tabatabai/
I would be very thankful if you would have a look into it.

The only Omega documentation I know is "omega-doc-1.8.tar.gz" in
/CTAN/systems/omega. You find there also the latest library stuff and
cweb sources for version 1.15. Concerning TeX ==> XML/MathML primitives
I must admit that they are totally unknown to me. Perhaps I have not
read the documentation carefully enough.

Behnam

There is absolutely no documentation for XML/MathML, except one article
in French by Yannis which is available at:
http://genepi.louis-jean.com/omega/lyonmathml.pdf
But it is very basic and doesn't say anything about the primitives
available. You can find the summary of this article in "Goossens et
al: LaTeX Web Companion" (MathML section).
I just scanned through the original Web sources of Omega and discovered
around 26 primitives (which seem to be sufficient to write a decent
filter package), the usage of which has been discovered through trial
and error.
Hans, Behnam, if you need these, I can send you the list of primitives
with usage I found, so that you can save a hell of time. Also, you can
help me, if you discover anything new. I am sorry to say that Yannis and
John Plaice are absolutely silent and didn't bother to reply any of my
mails on this problem.

We may continue this thread off list, but some aspects may be interesting
to others so let me for the moment use the list:
Your file says:
\font\OMARAB=omarab
far better is a definition like
\definefont[OMARAB][omarab sa 1]
because it adapts itself to the body font size. Even better, if the beta
version we change the following [i'll add it to the beta].
\def\dododefinefont#1#2%
{\parsefontspec[#2]{\bodyfontsize}{*#1*}\getvalue{*#1*}}
the \OMARAB\ command will now honor changes in size halfway the document
[for those interested: there is no real delay in resolving the font spec
each time and since persian is not used in math formulas, we don't need the
tex family concept here; this \definefotn mechanism is btw more powerful
than it may seem at first sight, since it scales, maps, etc quite nicely].
Then there is the OTP mechanism, which chains a series of filters. Whet we
need there is something similar, like (maybe we can leave the synonym here,
and auto resolve indirect mappings)
\definefiltersynonym [OTF8 to UNICODE16] [inutf8]
\definefiltersynonym [farsi to arabic] [FarsiToArabic]
\definefiltersynonym [preprocess arabic] [uni2cuni]
\definefiltersynonym [build arabic glyphs] [cuni2oar]
next there is:
\definefiltersequence[Farsi][OTF8 to UNICODE16, farsi to arabic, preprocess
arabic, build arabic glyphs]
[what is the 1000 in \ocplist\OCPListFarsiUTF=\addbeforeocplist 1000
\OCPutf ?]
[it's no problem to call sequences inside filter sequences]
now we can say:
\Farsi\OMARABIC
and get thoce nice sequences of glyphs. In this way we can hide the otp
interface and protect macros.
