Yes, I will add the bug.

BTW I once started to write a form editor which is schema
based similar 
to the approache described in
  http
://www.xml.com/pub/a/2003/04/30/editing.html
but at the moment i have no time to work on it and I am
anyway not sure 
whether it make sense to work on another (form) editor?

fwiw, i have some code lying around that will create a
skeleton lenya 
module with a form editor from a given (simple) rng grammar.

two problems are keeping me from releasing it:
* it got broken due to some recent svn changes, and i
haven't had the 
time to fix it.
* it is implemented in xsl 2.0 and would require to add the
saxon-8 jar 
to lenya. i would like to use it everywhere instead of the
old trax one, 
but again i have not found the time to work on it.

i think we should eventually try to create something like
that for 
lenya. the cforms editor is a nice example, but the downside
of cforms 
is that you need to modify so many different files, and most
of it is 
boilerplate stuff, so it would be nice to automate it.

if you're interested, i can upload it somewhere, but as i
said, it's not 
in working order, although the foundation is usable i think.

I was also thinking about generating a new module in 1.4.
But up to know, I could only generate a xslt out of the
schema. This 
xslt on the other hand generates a input field for all
elements in an 
xml-file.

I am very much interested in your work. Can you pack and
send it by mail 
or maybe better adding an "enhancment" bug in
the bugzilla and attach 
the file.

i generate all needed files from the schema in one pass.
most stuff is 
boilerplate code, but you always have all the schema
information 
available, so each file can be customized as you like.

it's here:
http://pol-serv1.politik.uni-duisburg-essen.
de/~nettings/rng2cforms/
http://pol-serv1.politik.uni-dui
sburg-essen.de/~nettings/rng2cforms-0.0.1.tar.gz

start with reading rng2cforms.xsl, it's the main stylesheet
that 
includes all the others. iirc there is a comment on how to
invoke it.
note that it only supports simple, russian-doll-style
grammars atm - no 
refs, no defines.

the package includes michael kay's saxon 8 for convenience,
so i'm not 
putting it on an apache server atm, since there will
probably be 
licensing issues.

before anyone asks: it is absolutely impossible to do that
kind of stuff 
in xstl1.0, so unless the xalan folk get up to speed, this
will have to 
be out-of-tree...


best,

jörn

Thank you for the pointer. I did download your work and will
have a look 
at it as soon as possible ....

Therfore i decided to do the first step in java in order to
resolve all 
includes and following all refs to their defs.
This class then generates the appropriate xslt-file.

supporting only a subset of rng was a design decision to
keep the 
prototype simple and get working results more quickly. it's
by no means 
impossible (actually quite easy since xslt2 supports
intermediary result 
trees) to support all internal and external refs with plain
xsl code.

as to my choice of language, it may be hard to believe for
anyone who 
has tried to solve nontrivial problems in xslt version 1,
but 
xslt2/xpath2 is actually beautiful and very pleasant to use,
mostly due 
to the fact that variables are no longer second-class
citizens and can 
contain usable trees, and to the introduction of
<xsl:function/>.


regards,

jörn

Nice to hear ....

1, but 

That's the reason why I did not even think of starting it
with xslt ....

So, I need to dig into xslt2/xpath2
