Opening normal user files in Symbian OS 9.1

One of the subjects that is not properly documented in the 9.1 SDK's that I 
have seen (including the S60 3rd beta and the UIQ 3.0 beta 2) is about 
opening normal user-visible files. There are Data caching issues here 
(documents passed around to viewers (UIQ) or document handlers (S60) that 
are stored as attachments in another app's private workspace), but none of 
this is documented at all. There is a new call 
CEikDocument::OpenFileL(CFileStore*& aFileStore, RFile& aFile), which is
not 
mentioned in any of the migration guides, or listed as a new method.

There is apparently also a connection with shared RFiles, anothed topic 
lacking documentation.

This is especially important for people opening non-native files, as the 
framework does less for you in that case.
