Update class_structure with AML?

Hi Kevin,

It appears that the class_structure property on ItemType is a Text field. Here's what it looks like for the Part ItemType:

I believe your issue is that you're treating the XML within the class structure as an extension of your AML, when in reality it's basically a long string within your class_structure property. I've created a basic ItemType with a modified class structure and exported it via the export tool. Here's how it looks:

It looks like the contents of the <Class_structure> tag are wrapped in a CDATA wrapper. your code should look like 

I'm curious why you're using AML for something like this? Generally going into the instance for a change like this would make more sense, where you can then export it and reimport if necessary.
