Remarks

The IMdElement provides access to model element's properties such as State and Valid, and its methods such as GetMessages and Validate.

MdElement objects are the items that define the contents of a model. A Model Process [IMdProcess] represents the invocation of a tool with its set of values. A Moel Variable [IMdVariable] represents a specific value that is used as input or output of one or more model processes.

The attached sample code show how to access a model process.
