Notes on PLISAXA and PLISAXB XML parsing support and differences with IBM's implementation

The following are considerations if migrating an existing z/OS based application:

• The event unknown_attribute_reference (E20), which is part of the PLISAXA and PLISAXB event structure (but not part of PLISAXC) is generated with the same content as IBM's SAX processor but occurs earlier in the parsing.
• The reference for the event unknown_content_reference (E21) is expanded to be its actual value.
• The events start_of_prefix_mapping (E22) and end_of_prefix_mapping (E23) are currently not supported to maintain compatibility with applications written using IBM's PLISAXA and PLISAXB functionality.
• When using the SAX Parser, the exception event (E24) is driven only one time indicating an error, as opposed to having the exception event driven one time per character. See the topic XML Parsing Exception Event error codes for a list of Micro Focus error codes for the exception event (E24).
• PLISAXB accepts filenames as the third parameter in the form file://filename under UNIX, where filename is the name of a UNIX file. The character string specifying the input file should have no leading or trailing blanks. If this is not the format, the parameter value is assumed to be the actual filename. Only files of RECFM=F, FB, FS, FBS and LSEQ are acceptable input.
