[sword-devel] OSIS formatting

[Greg Hellings]

I agree whole-heartedly that the move ought to be made away from style 
attributes and to class attributes. I suspect that it would not be 
exceedingly difficult to enable a module to contain a specification of an 
external stylesheet to be used with it (a new line in the conf file? 
automatically look for the existence of one?). The OSIS spec, in my 
recollection, indicates that CSS and XSL should be used to apply formatting, 
so adding that type of support would move closer towards conformance with 
the OSIS spec.

I am in support of presentation/data separation. But how can that be 
currently accomplished with OSIS in Sword is my main concern.
