Jpeg xmp schemas.

	Hi.
	I'm trying to parse the attached xmp extracted from a jpeg image using
apache-commons-imaging.
	I got the following error:
Cannot find a definition for the namespace
http://iptc.org/std/Iptc4xmpCore/1.0/xmlns/
org.apache.xmpbox.xml.XmpParsingException
	at
org.apache.xmpbox.xml.DomXmpParser.checkPropertyDefinition(DomXmpParser.java:858)
	at
org.apache.xmpbox.xml.DomXmpParser.parseChildrenAsProperties(DomXmpParser.java:295)
	at
org.apache.xmpbox.xml.DomXmpParser.parseDescriptionRoot(DomXmpParser.java:239)
	at org.apache.xmpbox.xml.DomXmpParser.parse(DomXmpParser.java:203)
	at org.apache.xmpbox.schema.TestJPegXmp.testNonStrict(TestJPegXmp.java:41)


	My understanding it that I must add the schmea to
org.apache.xmpbox.schema. Am I right ?
	There is any way to avoid that ?.
	Sombody can guide me trough the process ?

	Thanks in advance.

There is no process... you look at the source code to see how the other 
schemas are done. And you need a text that explains how this schema is 
defined.

http://iptc.org/std/Iptc4xmpCore/1.0/xmlns/

does have some links.
I'm surprised that Apache Commons Imaging are using xmpbox. Didn't know 
that.
