Detailed Description

The in-memory representation of an OSiL instance..

Remarks

1. Elements become objects of class type (the ComplexType is the class)

2. The attributes, children of the element, and text correspond to members of the class. (Note text does not have a name and becomes .value)

3. Model groups such as choice and sequence and all correspond to arrays

1. anything specific to XML such as base64, multi, incr do not go into classes
2. The root OSnLNode of each <nl> element is called ExpressionTree
3. Root is not called osil it is called osinstance

The OSInstance class is composed of two objects: the header object instanceHeader and the data object instanceData
