Re: [dita] Bug in XML catalog file

[Eric Sirois <esirois@ca.ibm.com>]

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,
Eric

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!

Hi,

today it was pointed out on xml-dev mailing list that there is error in
XML catalog file, see thread
http://lists.xml.org/archives/xml-dev/201112/msg00060.html

More precisely all <system> entries should be removed from the file
catalog-dita-xsd.xml

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

Thanks,
