>          Issue Type: Bug
>          Components: opencmis-commons

> We came across this issue in . This
is affecting Alfresco OpenCMIS Extensions.
> It would seem that the presence or absence of xalan.jar on the sending side can affect
the receivers ability to lookup attributes on an extension element.
> The two examples given at

> I think the lies in the way that OpenCMIS deserializes extension elements. It strips
the namespace from all attributes, loading their local name into a single map. That means
xmlns:propertyDefinitionId and propertyDefinitionId:propertyDefinitionId may be considered
to be the same attribute so one can overwrite the other.
> The attached patch to org.apache.chemistry.opencmis.commons.impl.Converter.convertDomToCmisExtensionElement()
fixed the issue for us, making it only pay attention to attributes in the element's namespace.
