If using the FLAGS parameter of the content_characters event as a BIT(8) array, you must take into account bit ordering differences on Intel from z/OS. If evaluated as a single byte and not a bit array, then bit ordering matches z/OS bit ordering. See the online help topic Bit (n) for a discussion of bit ordering in a bit array on little endian platforms.
If XML content contains predefined reference characters, separate content_characters events are driven for the characters preceding the predefined reference characters, the reference character, and the characters after the reference characters. For example, the XML snippet <meat>Ham & turkey</meat> generates three content_characters events using PLISAXC; one for Ham, one for &, and one for Turkey.
For the FLAGS parameter of the content_characters event, the flag to indicate the next event contains content_characters ('80'x). This currently only indicates if the next event contains content_characters when the current event contains a character which must be escaped back to XML. Also, the flag to indicate that no characters are escaped back to XML ('40'x) is only set if the character string contains one of the predefined reference characters for PLISAXA.
