Microsoft supports a SetClass method (I think so), where you can set the
content_type
of the storage. This identifies the code associated with the contents of
the storage, which seems to be useful (you simply know what is contained
in the storage). You can also get the type of a storage or stream with the
Stat method. Consider the case where a word document contains a excel sheet.
If I know the content type of the storage containing the excel sheet I can
extract it with (only as example) the file manager.

There are some advantages if we restrict ourselves setting the type of  a
stream/storage to the point in time when the stream/storage is created
- but only if we save to a storage which we can't access randomly.
(make only sense with my previous sequential storage suggestion).
