First, does module name equate to the osgi bundle symbolic name? We would also need additional policy information that equates to the Require-Bundle header parameters.

I guess, I can't see why one would want to use both syntaxes.

  |   | <classloading xmlns="urn:jboss:classloading:1.0">
  |   |    <capabilities>
  |   |       <module name="export1" version="1.0.0"/>
  |   |       <package name="export2"/>
  |   | 
  | The package export2 has version 0.0.0 if you are explicit.

Sure, this would be a reason to use the expanded syntax.

I don't see the difference between this and the export-all="ALL" included="..." notion. What is the difference?

What would the version be fixed up to? In terms of modules, unless its mapped to something usable like the deployment name, how would the fixed up name be usable?
