[relaxng-user] prep.xsl

[Cheng-Chang Wu]

I've found prep.xsl, thanks for the help.

My program can still not handle all of the relaxng
constructs, but it can already read the relaxng file I
am using in my project.

I've had problems to determine the nullability of ref
element. In section 4.19 of the specification it says
one can replace the expandable ref element with its
definition. THIS MUST NOT RESULT IN A LOOP. I can't
grasp this well. Ex.

<define name="test>
  <choice>
     <ref name="test">
     <element name="test"/>
  </choice>
</define>

Isn't this a correct relaxng schema? I don't know
Java, so I can't find how jing has done it. How can
this be simplified with the simplification rules in
section 4 of the specification?

I havn't done the simplification as the specification
says, will this bring me some trouble in the future?

Thanks for your great job on RelaxNG, it's much better
than any other schema language which I can't
comprehend.
