Re: [dita] DITA 1.2 Schema Issues

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

Hi Chris,

I'm not sure why the parser is complaining
about commonElementsGrp.xsd.  If there are issues, it should be with
commonElementsMod.xsd.  I removed references to the XML namespace
from files that did not make use of attributes within that file.  Having
those there was making MSXML complain about issues as well.   

Not sure why since the complaining.
I ran SCMPrint -f D:\dita1.2\doctypes\xsd1.2-url\technicalContent\xsd\map.xsd
using Xerces 2.6.0.  There are no issues returned.  I also ran
SAX2COUNT on the sample map.dita that points to the same map.xsd file and
it does not return any issues.

I did use the application XML Copy Editor
to validate some sample files. It uses Xerces-C to validate documents.
 It looks like it uses Xerces 2.8.0.

I tried opening the same map.dita sample
in our version of Arbortext Editor.  I get the following issue:

D:\dita1.2\doctypes\xsd1.2-url/base/xsd/commonElementMod.xsd
: Line: 2910 Column: 39
Could not find top level attribute:
xml:lang

I'm not sure why that error is popping
up.  The commonElementMod.xsd file does have a reference to xml.xsd.


As for the rest of the issue, unfortunately,
they are bugs.  We can fix those with an errata when then spec becomes
a recommendation.


Kind regards,
Eric

All,
 
I’m in the process of integrating the
latest DTD and Schema changes into the copies we have in our install tree
for the next release, and I think I’ve found some bugs in the schemas.
 
Firstly, schema-based maps are showing
errors about not being able to find xml:space and xml:lang top-level attributes
from commonElementsGrp.xsd.  I notice in the latest changes, Eric
removed the schemaLocation attribute from the import for the XML namespace.
 Is there a reason it was dropped?  It’s there other places
the namespace is imported (utilitiesDomain, programmingDomain, softwareDomain,
and uiDomain).  Adding it back causes our Editor to stop complaining.
 
Also, learningMapDomain.xsd misspells ‘locktitle’
(‘loctitle’). Looks like this dates back to when it was first added in
January, so it’s not a new bug.
 
Finally, the learning schemas have some
class attribute bugs.  The class attribute on lcLom is incorrectly
defined as “+ topic/metadata learning-d/lcLom” instead of “+ topic/metadata
learningmeta-d/lcLom”, and learningSummaryRef uses "- map/topicref
learningmap-d/learningSummaryRef " instead of "+ map/topicref
learningmap-d/learningSummaryRef " (- instead of +).
 
None of these problems are in the DTD versions.
I don’t know what the implications are for changing the schemas at this
point in the process, but I wanted to raise the issue.
 
Chris
 
P.S. Arbortext Editor has a Specialization
Validation tool (historically, incorrect customer specializations is one
of our major tech support headaches). It uncovered all but the first issue.
 Going forward, I’m happy to volunteer to run it on future changes
as they’re made as a sanity check.
