We will try to contemplate and think deeply about this issue.

Sure. Look at the MakeSIS documentation in the SDK. This one directly from the S60 3rd Ed. maintenance release SDK docs:
; A SIS file which embeds another

;Languages
&EN,GE

;Header
#{"Embedding-EN", "Embedding-GE"}, (0x10000017), 1, 2, 3

%{"Vendor", "Verkaufer"}
:"Vendor"

;Embedded component
IF NOT package(0x80000002)
@"sub.sis",(0x80000002)
endif

;Ordinary file to fixed drive
{
"text\englishfile.txt"
"text\germanfile.txt"
}-"C:\private\10000018\import\lang.txt"

;Ordinary file to selected drive
"text\file1.txt"-"!:\private\10000018\import\file1.txt"

;Display a text file
"text\textfilec.txt"-"", FT, TC
