The default depends on how've you created the parser. JAXP says the default is
false [1]. SAX says the default is true [2]. There isn't a bug here. It's just
a conflict between the two specs which often burns users who assume that SAX
and JAXP are consistent. Glancing at the source code for XMLValidateTask [3]
and JAXPUtils [4] a non-namespace aware JAXP SAXParser is being created and
used.
As to whether namespace support is required for schema processing and
validation, it's not specific to Xerces. W3C XML Schemas are built upon XML
namespaces (among other standards).

Key: XERCESJ-979
Summary: default of the feature "http://xml.org/sax/features/namespaces"
Type: Bug
Status: Resolved
Priority: Major
Resolution: INCOMPLETE
Project: Xerces2-J
Versions:
2.6.2

Reporter: Antoine Levy-Lambert

Description:
I have been working on a bug report http://issues.apache.org/bugzilla/show_bug
.cgi?id=29187 titled "xmlvalidate schema validation not working".
I found out that if the following XML fragment is added to <attribute name=
"http://xml.org/sax/features/namespaces" value="true"/> the body of the
xmlvalidate tag in the ant project file, then the validation works.
But the documentation of xerces says that the namespaces feature defaults to
true.
http://xml.apache.org/xerces-j/features.html
So I suspect one of 3 possibilities :
- documentation bug : the default of the feature is false,
- code bug : the intended default for this feature is true, but the code sets
it to false or "forgets" to set it explicitly to true
- something specific for the xml schema validation implementation present in
xerces ???
I will add the feature to one of the examples in the documentation of ant.
Cheers,
Antoine
