Meaning of sif file entries

[skagway095]

Hi,

this is a line of the [SourceDisksFiles] section of a .sif file:
glosW.chm = 1,,,,,,,21,0,0,Glossary.chm

Does anyone know what all these parameters mean, especially those missing ones and the numbers?
Microsoft's official description http://msdn.microsoft.com/library/d..._98e4d013-4846-474d-8ccd-eb5ec33b67ee.xml.asp

filename = diskid[,[ subdir][, size]]

is at least very incomplete for it mentions only 3 parameters while we have 11 possible parameters here.
