/**
* A debug element represents an artifact in a program being

* <p>
* Some methods on debug elements require communication
* with the target program. Such methods may throw a <code>DebugException</code>
* with a status code of <code>TARGET_REQUEST_FAILED</code>
* when unable to complete a request due to a failure on the target.
* Methods that require communication with the target program or require
* the target to be in a specific state (for example, suspended), are declared
* as such.
* </p>
* <p>
* Debug elements are language independent. However, language specific
* features can be made available via the adpater mechanism provided by
* <code>IAdaptable</code>, or by extending the debug element interfaces.
* A debug model is responsible for declaring any special adapters
* its debug elements implement.
* </p>
* <p>
* Clients may implement this interface.
* </p>
* <p>
* <b>Note:</b> This class/interface is part of an interim API that is still under development and expected to
* change significantly before reaching stability. It is being made available at this early stage to solicit feedback
* from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken
* (repeatedly) as the API evolves.
