XMI and determining if a column allows nulls.

[scyoung]

Hi Guys,

I am busy writing an XSL style sheet that will generate .Net code from an XMI document.  We have a legacy database that we need to encapsulate in objects.

I have imported the database into EA to get a DataModel.  I then export this package to an XMI document that I run an XSL transform against.  

The problem I am having is that we have nullable types to support nulls in our object model.  So I need to determine if a column is nullable or not.  I can't seem to find out where in the XMI that info is stored.  Any ideas?

Thanks,
Stephen
