In contents supervisor speak, an extent list contains header information and then information about the length and address of each (module) extent (whether mapped by IHAXTLST or IHAXTL64.
As the name implies, XTL64E_EXTENTADDR contains the address of the extent for this entry. And, not surprising, there is a similar field, also appropriately named, that contains the length of the extent. Applying both to XTLST and XTL64, it is relatively uncommon to need to know the information about the extents unless dumping the module. The entry point address is more common to use. Since you didn't provide any information about what you were intending to do with the information, I have no idea which would be better for you.
