Modification of char xml schema

[Francois Bonnarel]

In order to integrate ta very last change in STC schema
announced by Arnold last Friday ( common Substitution groups for
1D 2D 3D Coordiante values, errors, sizes resolution and pixsizes ...)
we  modified the characterisation schema in order to reuse these stc
subst groups instead of rebuilding them as we were doing previously ...


Cheers
Françis
