- * how Excel represents different formats (e.g., one word
- * plain and one word bold).

+ * For a more advanced implementation of SAX event parsing

+ * and {@link XSSFSheetXMLHandler}. Note that some use cases,
+ * it may be possible to simply use those with a custom
+ * {@link SheetContentsHandler} and no SAX code needed of
