-The @racket[_block-txexpr-proc] argument and the @racket[_inline-txexpr-proc] arguments are procedures that operate on tagged X-expressions. If the X-expression meets the @racket[block-txexpr?] test, it is processed by @racket[_block-txexpr-proc]. Otherwise, it is processed by @racket[_inline-txexpr-proc]. Thus every tagged X-expression will be handled by one or the other. Of course, if you want block and inline elements to be handled the same way, you can set @racket[_block-txexpr-proc] and @racket[_inline-txexpr-proc] to be the same procedure.

(Careful, however — these aren't mutually exclusive, because @racket[_block-txexpr-proc] operates on all the elements of a block, including other tagged X-expressions within.)
