The following is the complete grammar for Hessian 1.0. All integers are big-endian, i.e. starting with the most-significant byte first.

top     ::= call
        ::= reply

call    ::= c x01 x00 header* method object* z

reply   ::= r x01 x00 header* object z
        ::= r x01 x00 header* fault z

object  ::= null
        ::= boolean
        ::= int
        ::= long
        ::= double
        ::= date
        ::= string
        ::= xml
        ::= binary
        ::= remote
        ::= ref
        ::= list
        ::= map

header  ::= H b1 b0 header-string object
method  ::= m b1 b0 method-string

fault   ::= f (object object)*

list    ::= V type? length? object* z
map     ::= M type? (object object)* z
remote  ::= r type? string

type    ::= t b1 b0 type-string
length  ::= l b3 b2 b1 b0

null    ::= N
boolean ::= T
        ::= F
int     ::= I b3 b2 b1 b0
long    ::= L b7 b6 b5 b4 b3 b2 b1 b0
double  ::= D b7 b6 b5 b4 b3 b2 b1 b0
date    ::= d b7 b6 b5 b4 b3 b2 b1 b0
string  ::= (s b1 b0 string-data)* S b1 b0 string-data
xml     ::= (x b1 b0 xml-data)* X b1 b0 xml-data
binary  ::= (b b1 b0 binary-data)* B b1 b0 binary-data
ref     ::= R b3 b2 b1 b0
