It is not complete but here you can see the basic structure:

(There is something wrong in that image.. deroad)

Offset	Length	Type	Information
0x0	0x8		Magic
0x6	0x2		Package Version
0x08	0x2		Image Version
0x18	0x8		File Count
0x10	0x8	??	UNKNOWN
0x20	0x8		Header Length
0x28	0x8		File Length

Regioning

If simular to PS3, then there is no regioning in the .PUP files, they are the same for all different regions.
The PS Vita however gets the psp2-updatelist.xml from different servers, depening on the region of that model.
