Description Vlad Gheorghe CLA 2011-11-04 18:17:15 EDT 
It would be useful that the prefix used to reference to an imported package in a MTL module to be defined by the user.

The enhanced syntax would be like:
<mtl>
module Mod1(mymm1='http://example.org/mm1/1')
</mtl>

Note. This feature is similar to xml namespaces.
e.g.
<elem  xmlns:mymm1='http://example.org/mm1/1'>
  <mymm1:A/>
</elem>

I think 

    module Mod1(mymm1:'http://example.org/mm1/1')

would be more consistent with other name:type declarations.

The syntax  name:Type  is used to declare new local variables and parameters, with the given name.
  (  <variable> ':' <type> )


In the case at hand the name is just an alias for an *existing* package (hence the equivalence '=' sign ).

IMHO, using the same syntax would be confusing.

Could be interesting for disambiguation of types sharing the same namespace as well.
