schema content model question

I have been attempting to create an XML Schema content model for an
element like the following:

- the element should contain text only, no subeleemnts (simpleContent?)
- the permissable values of the element should be restricted to a list of
enumerated string values
- the element should also have attributes with values which are also
restricted to list of enumerated string values.

Is this possible? I have made several attempts which I will send if it is
useful for discussion but I thought perhaps someone can just provide the
answer.

thanks,
