[news.eclipse.modeling.m2m] Re: [ATL] XML extraction with ATL 3.0

[rbarrett@xxxxxxxxxxxxxxxx (Ronan )]

Hey William,
Thanks for that. Would it be possible to say this is not implemented in 
the wiki handbook as i'm sure many other people will hit this problem.

I'm trying out your second solution. However, if I create a model 
conforming to the EMF XSD I won't have control over how it is formatted as 
precisely as I would with the old XML.ecore based approach. For example 
namespaces will be used and element names will look different e.g. 
ModelType instead of Model. I need very fine grained control over how the 
XML will look for interoperability.
Cheers,
Ronan
