Subject: Re: [dita] Bug in XML catalog file

Hi Don,

I would agree with Michael that <uri> would the proper semantic as per the spec.  That said, <system> is in the catalogs so that it can work properly with the Apache catalog resolver and SAX.   Using <uri> does not work properly with the catalog resolver when you have a XSDs that does not have a namespace.  I've had a number of chats with the developers regarding the issue a while back. They have acknowledged bug(s) on both the resolver side and Xerces, but it's not something that's is going to be fixed anytime soon.

Though it may be technically wrong, it's the only way things work at the moment, in part, because DITA don't have namespace(s) associated with the XSDs. 

<system> is there so that it can work with what's currently available as an open source resolver.
<uri> is there so that a resolver that is fully implemented as per the OASIS Entity spec can find the documents.

Kind regards,

This is sufficient, Jirka.  John Cowan's explanation provides good background for how the practice was apparently originally adopted. Curious that it was promulgated without detection for so long!

today it was pointed out on xml-dev mailing list that there is error in
XML catalog file, see thread

More precisely all <system> entries should be removed from the file

Is my email sufficient for fixing this in another release, or should I
file bug somewhere?
