- * VOL_CAP_FMT_2TB_FILESIZE: When set, the volume format supports file 
- * size upto 2TB.  This bit does not necessarily mean that the file 
- * system does not support file size more than 2TB.   This bit does 
- * not mean that the currently available space on the volume is 2TB. 
+ * VOL_CAP_FMT_2TB_FILESIZE: If this bit is set the volume format supports
+ * file sizes larger than 4GB, and potentially up to 2TB; it does not
+ * indicate whether the filesystem supports files larger than that.
+ *
+ * VOL_CAP_FMT_OPENDENYMODES: When set, the volume supports open deny
+ * modes (e.g. "open for read write, deny write"; effectively, mandatory
+ * file locking based on open modes).
+ *
+ * VOL_CAP_FMT_HIDDEN_FILES: When set, the volume supports the UF_HIDDEN
+ * file flag, and the UF_HIDDEN flag is mapped to that volume's native
+ * "hidden" or "invisible" bit (which may be the invisible bit from the
+ * Finder Info extended attribute).
+ *
+ * VOL_CAP_FMT_PATH_FROM_ID:  When set, the volume supports the ability
+ * to derive a pathname to the root of the file system given only the
+ * id of an object.  This also implies that object ids on this file
+ * system are persistent and not recycled.  This is a very specialized
+ * capability and it is assumed that most file systems will not support
+ * it.  Its use is for legacy non-posix APIs like ResolveFileIDRef.
+ * 
+ * VOL_CAP_FMT_NO_VOLUME_SIZES: When set, the volume does not support 
+ * returning values for total data blocks, available blocks, or free blocks
+ * (as in f_blocks, f_bavail, or f_bfree in "struct statfs").  Historically,
+ * those values were set to 0xFFFFFFFF for volumes that did not support them.
+ * 
+ * VOL_CAP_FMT_DECMPFS_COMPRESSION: When set, the volume supports transparent
+ * decompression of compressed files using decmpfs.
+ *
+ * VOL_CAP_FMT_64BIT_OBJECT_IDS: When set, the volume uses object IDs that
+ * are 64-bit. This means that ATTR_CMN_FILEID and ATTR_CMN_PARENTID are the
+ * only legitimate attributes for obtaining object IDs from this volume and the
+ * 32-bit fid_objno fields of the fsobj_id_t returned by ATTR_CMN_OBJID,
+ * ATTR_CMN_OBJPERMID, and ATTR_CMN_PAROBJID are undefined.
+ *
+ * VOL_CAP_FMT_DIR_HARDLINKS: When set, the volume supports directory
+ * hard links.
+ *
+ * VOL_CAP_FMT_DOCUMENT_ID: When set, the volume supports document IDs
+ * (an ID which persists across object ID changes) for document revisions.
+ *
+ * VOL_CAP_FMT_WRITE_GENERATION_COUNT: When set, the volume supports write
+ * generation counts (a count of how many times an object has been modified)
+ *
+ * VOL_CAP_FMT_NO_IMMUTABLE_FILES: When set, the volume does not support
+ * setting the UF_IMMUTABLE flag.
+ *
+ * VOL_CAP_FMT_NO_PERMISSIONS: When set, the volume does not support setting
+ * permissions.
