Re: [xml-dev] Trang conversion of XML to rnc -- choices not preserved

[George Cristian Bina <george@oxygenxml.com>]

Hi Alex,

I have no problem converting your sample from RNG to RNC [1].
My guess is that you hit another issue with the command line usage. If 
you do not specify the input and output types with the -I and -O command 
line options then Trang will guess from the extension (as documente on 
http://www.thaiopensource.com/relaxng/trang-manual.html#arguments) and 
for .xml it will infer XML input while what you want is RNG input. 
Either use docWithoutIncludes.rng instead of docWithoutIncludes.xml for 
the RNG schema or specify -I rng in the command line.

[1] sample rng to rnc

***
<?xml version="1.0" encoding="UTF-8"?>
<grammar
     xmlns="http://relaxng.org/ns/structure/1.0";
     xmlns:a="http://relaxng.org/ns/compatibility/annotations/1.0";
     datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes";>
     <start>
         <element name="x">
             <choice>
                 <value type="token" datatypeLibrary="" ns="">AAA</value>
                 <value type="token" datatypeLibrary="" ns="">BBB</value>
                 <value type="token" datatypeLibrary="" ns="">CCC</value>
             </choice>
         </element>
     </start>
</grammar>

***

namespace a = "http://relaxng.org/ns/compatibility/annotations/1.0";

start = element x { "AAA" | "BBB" | "CCC" }

Best Regards,
George
