Hi,

I have a question concerning a metadata unmarshalling issue. In my 
project I have created an Extensions element to Organization in an 
EntityDescriptor, in order to map certain data objects as children of 
the Extensions element.  For this I've used 
AttributeExtensibleXMLObject, as I would like to map a certain piece of 
information as an attribute to an Extensions child. Here is the code 
I've used (the attribute is called matchAlgo):

    Extensions extensions = extensionsBuilder.buildObject(extQName);
    AttributeExtensibleXMLObject extension = 
(AttributeExtensibleXMLObject) 
defaultBuilder.buildObject(extensionsChildQName);
    QName matchAlgoQName = new QName(HLPattern.EGHL_NS, 
HLPattern.MATCH_ALGO_NAME, HLPattern.EGHL_PREFIX);
    
extension.getUnknownAttributes().put(matchAlgoQName,hlPattern.getMatchingAlgo());
    extensions.getUnknownXMLObjects().add(extension);

The marshalling for this works very well, but I have trouble with 
unmarshalling for retrieveing the value of the attribute. Looking at the 
debug logs, I see that the matchingAlgo attribute is found and read, and 
the processAttribute() function is called. But then I don't seem to 
manage to retrieve its value; can you please tell me what is the right 
way to do so?

Something like extension.getUnknownAttributes().get(0) or 
((ElementProxy)extesion).getUnknownAttributes().get(0) doesn't seem to 
work, it returns null.

Regards,
