UPDM — UPDM XMI contains properties with incorrect lower values

There are a number of properties and possibly extension ends in both the model library xmi and the profile xmi that contain the following:

<lowerValue xmi:type="uml:LiteralUnlimitedNatural" xmi:id="..." visibility="public" value="*"/>

This isn't valid. Lower values need to be integers and clearly it also doesn't make sense for the lower bound to be unlimited. Almost certainly these ought to be uml:LiteralInteger instances with value="0".

Remove the line relating to the lower value in the XMI if it is 0, if default vaue is not 0 then make appropriate changes. Parser needs to be tweaked. Aurelijus/Tomas needs to be checked when regenerating XMI
