* If an empty sequence is bound, {{Code|empty-sequence()}} must be specified as type
An Example: the three items {{Code|xs:integer(1)}}, {{Code|xs:integer(2)}} and {{Code|xs:string('A')}} are encoded as {{Code|1}}, {{Code|\1}}, {{Code|2}}, {{Code|\1}}, {{Code|A}}, {{Code|\2}}, {{Code|xs:string}}, {{Code|0}} (and <code>{{Code|xs:integer}}, {{Code|0}} </code> as general type).
As can be seen in the table, all results end with a single {{Code|\0}} byte, which indicates that the process was successful. If an error occurs, an additional byte {{Code|\1}} is sent, which is then followed by the {{Code|error}} message string.
