All PLISAXA and PLISAXB event functions must return a BYVALUE FIXED BIN(31) value that is a return code to the parser. For the parser to continue normally, this value should be zero.
For the first argument, the event functions pass a POINTER. This is the token value passed originally as the second argument to the built-in function.
With the following exceptions, all of the functions will also be passed a POINTER and a FIXED BIN(31) that supply the address and length of the text element for the event. The following functions and events are different:
| end_of_document | No argument other than the user token is passed. |
| attribute_predefined_reference | In addition to the user token, one additional argument is passed: a CHAR(1) or, for a UTF-16 document, a WIDECHAR(1) that holds the value of the predefined character. |
| content_predefined_reference | In addition to the user token, one additional argument is passed: a CHAR(1) or, for a UTF-16 document, a WIDECHAR(1) that holds the value of the predefined character. |
| attribute_character_reference | In addition to the user token, one additional argument is passed: a FIXED BIN(31) that holds the value of the numeric reference. |
| content_character_reference | In addition to the user token, one additional argument is passed: a FIXED BIN(31) that holds the value of the numeric reference. |
| processing_instruction | In addition to the user token, these additional arguments are passed:

| exception | In addition to the user token, these additional arguments are passed:
