Logical Structure Types
This extension point allows debuggers to present alternative logical structures of values. Often, complex data structures are more convenient to navigate in terms of their logical structure, rather than in terms of their implementation. For example, no matter how a list is implemented (linked, array, etc.), a user may simply want to see the elements in the list in terms of an ordered collection. This extension point allows the contribution of logical structure types, to provide translations from a raw implementation value to a logical value.

id - a unique identifier for this logical structure type
description - a description of this logical structure. Since 3.1, this attribute is optional. When unspecified, a logical structure type delegate must also implement
ILogicalStructureTypeDelegate2 to provide descriptions for values that logical structures are provided for.

ILogicalStructureTypeDelegate. The class may optionally implement

The following is an example of a logical structure type extension point:
In the example above, the specified logical structure type will be consulted for alternative logical values for values from the
debug model as they are displayed in the variables view.
