The handling of character sets in the multi-byte version is more sophisticated. The character sets HTML page gives more information. SP has built-in knowledge of many more base character sets . This allows parsing of well-formed XML documents, whether or not valid. There is now generalized support for architectural form processing .
Documentation is now in HTML format.
A BASE catalog entry can be used to specify a base system identifier for resolving relative storage object identifiers occurring in the catalog. Programs have a -E option that sets the maximum number of errors. SP can be built as a DLL under Win32. The syntax of system identifiers has completely changed. It applies to each entry individually rather than to the entire catalog.
