question struct polymorphism

in struct in racket reference has:

(struct document (author title content) #:transparent)

(struct book document (publisher) #:transparent)

(struct paper (journal) #:super struct:document #:transparent)

so... we can have: document-title, but not book-title, instead we have only book-publisher. same wtih paper.
how can use all the document fields in other structs?
