I am not sure what you want: remark that iTunes does not display certain fields?
Then please turn to the iTunes forum and ask them.
Or if this is pointless, then perhaps a different player with the ability to show also custom fields would be a better choice (e.g. foobar2000).
Or do you want to create a field that can be filled with the data you mentioned?
To create a new field, open the extended tags dialogue
Press the "New" button next to the fields list.
Enter the name of the field.
Enter the value.
Click OK until all dialogues are closed.
You can store this information in a user-defined field until you find a field in your favourite player. And then you can copy the information from the user-defined field to the displayed one.
There is already a field for COMPILATION.
And if I look at the list more closely I think that it is a mixture of media (EP, single), genre (e.g. SpokenWord would have the equivalent Speech in the list of genres), contents description (audiobook, interview, album) and track version (Remix, live as opposed to the e.g. album version or radio edit).
This will make it hard to find a field that groups this together as the information is already split across several other fields.
