* \brief Maximum valid Check ID
*
* The .xz file format specification specifies 16 Check IDs (0-15). Some
- * of them are only reserved i.e. no actual Check algorithm has been assigned.
- * Still liblzma accepts any of these IDs for future compatibility when
- * decoding files. If a valid but unsupported Check ID is detected, liblzma
- * indicates a warning with LZMA_UNSUPPORTED_CHECK.

- * FIXME bad desc
+ * of them are only reserved, that is, no actual Check algorithm has been
+ * assigned. When decoding, liblzma still accepts unknown Check IDs for
+ * future compatibility. If a valid but unsupported Check ID is detected,
+ * liblzma can indicate a warning; see the flags LZMA_TELL_NO_CHECK,
+ * LZMA_TELL_UNSUPPORTED_CHECK, and LZMA_TELL_ANY_CHECK in container.h.
