Description

Using feature "http://xml.org/sax/features/namespace-prefixes" breaks Jelly.

SAXParserFactory pf = SAXParserFactory.newInstance();
pf.setValidating (false);
pf.setNamespaceAware (true);
pf.setFeature ("http://xml.org/sax/features/namespace-prefixes", true);
XMLReader reader = null;
SAXParser parser = pf.newSAXParser();
reader = parser.getXMLReader();

InputSource inSrc = new InputSource
(new FileReader(new File ("util/test.jelly")));

Jelly jelly = new Jelly();
JellyContext context = new JellyContext ();

ExtXMLParser jellyParser = new ExtXMLParser ();
jellyParser.setContext(context);
jellyParser.configure ();

reader.setContentHandler(jellyParser);
reader.parse (inSrc);

Script script = jellyParser.getScript ();
script.compile ();
script.run (context, XMLOutput.createXMLOutput(System.out));

results in:

[junit] org.apache.commons.jelly.JellyTagException: null:-1:-1: <null>
null:2:88: <j:jelly> This tag does not understand the '' attribute
[junit] at
org.apache.commons.jelly.impl.TagScript.handleException(TagScript.java:600)
[junit] at org.apache.commons.jelly.impl.TagScript.run(TagScript.java:239)
[junit] at org.apache.commons.jelly.impl.ScriptBlock.run(ScriptBlock.java:89)

The offending line is "pf.setFeature
("http://xml.org/sax/features/namespace-prefixes", true)"

While setting this feature is, of course, not necessary for Jelly, the Jelly
script I want to use in the real application is embedded within a larger XML
file. This file is parsed into a SAX event buffer with the feature set (because
in general, namespace-prefixes are needed). The SAX events belonging to the
Jelly script are then "extracted" and fed to Jelly. Of course, I can filter out
the namespace prefix attributes (and I will, as a workaround). But Jelly should,
of course, not break because of these attributes being reported.
