Just a reminder: make sure you validate style files against the schema  
before checking them in. There are a lot of errors.

If there are problems you can’t fix, just post here.

Hello Bruce,

Your remarks about validating make sense. However, it seems to be  
quite a challenge to validate anything against Relax NG Compact. XML  
Nanny barks at it, xmllint doesn’t understand the compact version,  
and Jing spits out this:

[Johan-Kools-PowerBook:~] jkool% java -jar /Users/jkool/Downloads/  
jing-20030619/bin/jing.jar /Users/jkool/Developer/Biblio/csl/schema/  
trunk/csl.rnc /Users/jkool/Developer/Biblio/csl/styles/apa.csl  
/Users/jkool/Developer/Biblio/csl/schema/trunk/csl.rnc:1:1: fatal:  
Content is not allowed in prolog.

Is there an easy way to validate? I know you use Oxygen, but I don’t  
quite feel like buying it just to validate xml files. I hope I am not  
missing something obvious here…

I think the easiest, best option is to install this:

[http://www.davidashen.net/rnv.html](http://www.davidashen.net/rnv.html)

If you don’t have the time for that (it’s easy to compile, but you do  
have to compile it), you can convert to the XML syntax using Trang. Am  
attaching a version just in case.

Also, the excellent nXML mode (bundled with the equally excellent Aqua  
emacs) gives you real-time RNC valdiation and completion (though IIRC  
correctly, you’re not an emacs user).
