Is there any available VBP (Visual Basic 6 Project) file documentation?

Question

Is there any available documentation on the Keys/Values used in the VBP (Visual Basic Project) file? I'm trying to achieve a better understanding of how VBP handles references internally.

Example Line:

Reference=*\G{BF204980-5E29-4945-AEB5-DDB284C568D3}#1.0#0#..\Project1.dll#Project1

The syntax of references is described in [MS-OVBA]:

LibidReference     = "*\" LibidReferenceKind LibidGuid 
                     "#" LibidMajorVersion "." LibidMinorVersion 
                     "#" LibidLcid 
                     "#" LibidPath 
                     "#" LibidRegName

<LibidReferenceKind>: 

%x47 (G) <LibidPath> specifies a Windows file path.

%x48 (H) <LibidPath> specifies a Macintosh path.    

<LibidGuid>: The GUID of the Automation type library.

<MajorVersion>: An unsigned integer that specifies the
major version of the Automation type library.

<LibidMinorVersion>: An unsigned integer that specifies the
minor version of the Automation type library.

<LibidLcid>: The LCID of the Automation type library.

<LibidPath>: The path to the Automation type library.

<LibidRegName>: The Automation type library’s display name
