Document Context
In Visual Studio debugging, a document context:
Represents a position in a source file. For languages where the source file may not be present, a document context identifies a position in a document typically generated by the run-time environment. For example, a scripting engine might generate a document from script. For more information, see Document Position.
Describes a position in a source document that corresponds to a code context. The symbol handler maps a code context to documentation context, using information generated by a compiler or interpreter.
Is implemented by an IDebugDocumentContext2 interface.
