It doesn't *look* like what you are trying to do. The document defines 
'script categories'; what it should define is 'justification 
categories'. You probably have those categories defined elsewhere: de 
facto working definitions, at least, based on the kinds of behaviours 
that are permitted when breaking and justifying lines. So rather than 
creating a new set of named categories for scripts, why not name the 
sets of justification behaviours, and populate these as categories with 
scripts? I believe you will find instances in which the superficial 
characteristics of the scripts that the currently proposed script 
categories try to capture do not correspond to correct justification 
behaviour for those scripts, and this can be avoided by mapping the 
scripts directly to justification behaviour rather than into script 
categories first.
