   Not far-fetched, a real piece of cake!

   Only that it will perhaps be another level of abstraction than that
at which SWML is operating at the moment. Currently, it is operating at
the level of the graphical representation of the signs, as a simple
translation of the numerical description of the SignWrirint picture.

   Adding information like the possible range of values seems to me to
go beyond that very low level of description. It brings information that
concerns things outside the scope of the visual representation of a
(standard) way of making a sign.

   It goes into semantical and pragmatical issues. To me, this would
mean a new level of operation for SWML. Let as name SWML Level 0 the
current level. Other SWML levels would have to be defined: SWML Level 1,
SWML Level 2, etc., according to the complexity of the issues that are
added to the representation of the sign, going beyond the representation
at the basic level.

   Perhaps the information you are considering should be the information
that defines SWML Level 1. Perhaps there are other more fundamental
information that can define SWML Level 1, and the information you
mention be put into Level 2.

   Defining such SWML levels would be very important, I think, for
widening the application of SignWriting to other kinds of software,
besides text editors and simple databases (dictionaries).

   But interesting as it may be, that is certainly a task beyond my
reach. I can try to support anyone interested in trying it, but surely I
cannot go very far along that way.

   All the best,

   Antônio Carlos
