--------------------------------------
Hi Radu,
Just want to confirm the changes that you're suggesting.
1) In org.apache.xerces.impl.xs.XSDDescription
a) equals()
else // fNamespace == null
if (desc.getLiteralSystemId() != null) //added if statement
to check and use systemID.
return
fLiteralSystemId.equals(desc.getLiteralSystemId());
else return desc.getTargetNamespace() == null;
}
b) return (fNamespace == null) ? fLiteralSystemId.hashCode() :
fNamespace.hashCode(); //added fLiteralSystemId.hashCode() after ? instead
of existing 0
2)in org.apache.xerces.impl.xs.XMLSchemaValidator.findSchemaGrammar(short,
String, QName, QName, XMLAttributes)
if (grammar == null) {
fXSDDescription.setNamespace(namespace);
fXSDDescription.setLiteralSystemId(fExternalNoNamespaceSchema);
//add this line
I recompiled xercesImpl.jar and used it in DITA OT 1.6 to process
doc/articles/DITA-articles.ditmap where the map and DITA-domains.xml are using
XSD for validation instead of DTDs and it working fine.

> Xerces grammar pool not working with no namespace XSDs
> ------------------------------------------------------
>
> Key: XERCESJ-1595
> URL: https://issues.apache.org/jira/browse/XERCESJ-1595
> Project: Xerces2-J
> Issue Type: Bug
> Components: XNI
> Affects Versions: 2.11.0
> Reporter: Eric Sirois
> Fix For: 2.11.0
>
>
> When loading XSDs with no namespace into the Xerces grammar pool, it assumes
> every XSD with no namespace to be the same XSD doc. In our case, when trying
> to validate DITA documents, there could be a number of different types of
> documents involved, for example map, topic, task and concepts.
> To get around the issue we need to ignore XSDs when loading the grammar pool.
> This affects the time needed to produce/transform documentation
> significantly.
> If a namespace is available for the XSD, the grammar cache should use that.
> If the there is no namespace available, then it should use the system ID of
> the schema.
