yep, since they are widely used

Nothing can ever cover every function key that ever existed or could 
exist (just as DocBook doesn't cover every possible documentation 
markup). If you can't remember what the meta keys were on a 3270 and a 
VT100/220, then I don't see much reason to include them. But they could 
still be included; IMHO it's not a big problem if the enumerated list 
for the attribute is 20 instead of 10 values, or 30 instead of 20.

Yep; thanks for your help :)

those are in the list already

feel free to add those to the list on the RFE page

... and as I think I said, the list is just a first draft (I wrote 
"starting point"); it is not yet complete (where complete means all the 
stuff which is widely used).

My requirement, as I said, is to be able to markup input comands as 
such, without relying on arbitrary ASCII renderings which are not 
standardized in the DocBook spec. The exact syntax is not relevant for 
me. But your question could probably be answered as:

<keycombo action="simul">
   <keycap function="control"/>
   <keycap function="alt"/>
   <keycap function="backspace"/>
</keycombo>

<keycombo action="simul">
   <keycap function="alt"/>
   <keycap function="shift"/>
   <keycap>I</keycap>
</keycombo>
