option 1: bad card domain, change card domain (or card).

the CAP file's size should be used if:
- "installing" means "loading the CAP file" and
- "applet size" means "size need to store that library".
(if so, the card is quite stupid, since this information
is usually in the first 256 bytes of the CAP file)


option 2: card domain with memory allocation controls

OOH, if
- "installing" means "instantiating the applet" or
- "applet size" means "size needs during instantiation
  to manage allocation in its constructor", the response
  is up to you and only defined by what you have insert
  in your applet constructor.
 (of course if instance, array, ..., instantiation is
 also required during the applet's life you want take
 such figures into account when computing that "needed
 size").

and such information makes sense for a card domain.
