module.i_prefixes bug (only with DSDL plugin)

[GoogleCodeExporter]

If you try to generate DSDL from the "prefixes" module which I provide in the 
attachments it will break the plug-in. The modules which I provide are just 
dummies based on the quagga module which we got from tailf (Martin probably 
knows it). 

Anyways the main module (prefixes) specifies a submodule (prefixes-common) 
which imports another module (sample-extensions) and uses an extension from it. 
This extension breaks the plug-in in function dsdl.handle_extension(self, stmt, 
p_elem) because of the following call:

(modname,rev)=self.module.i_prefixes[prf]

since i_prefixes does not contain the prefix specified for the extension.

I think this is a bug in pyang not in DSDL plugin. i_prefixes of the main 
module does not appear to contain prefixes which are used within submodules yet 
it "inherits" all content from them including the offending extension. This 
means that the main module may contain extensions for which a binding in 
i_prefixes does not exist. I'm not entirely sure who's at fault here though.

It was a bug in the DSDL plugin.
