Raymond Lai commented on TUSCANY-2631:
--------------------------------------

The same kind of fault tolerance should be there for Import/Export processors as well.

>          Issue Type: Bug

>    Affects Versions: Java-SCA-1.3

> Currently, the Contribution model's StAXProcessor doesn't tolerate Contribution XML document that doesn't conform to the specification. For example, 
> <?xml version="1.0" encoding="UTF-8"?>
> <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0">
> 	<deployable composite="ns1:dfsdf" xmlns:ns1=""></deployable>
> 	<deployable  xmlns:ns1="http://temp"></deployable>
>         <deployable composite="ns1:aaaa" xmlns:ns1="http://temp"></deployable>
> 	<deployable composite="ns1:dsfs" xmlns:ns1="http://temp"></deployable>
> </contribution>
> Note that the first <deployable> element has an empty string namespace while the second <deployable> is missing the composite attribute. These errors will choke the contribution StAXProcessor and its read method returns a NULL. So that the other valid deployable composites are not read. 
> I think a more desirable approach to handle it is to read as much as possible and returns a Contribution object that contains both the valid composites and invalid composites which can be a sub-class of Composite, e.g. InvalidComposite. Also, the StAXProcessor should be able to write back the invalid composites.  
> This behaviour might be needed by other StAXProcessors as well, e.g. the composite's.
