Is a script an authoring tool?

This is a serious question from my point of view, and one that may be 
need to be addressed in ATAG.  WCAG does address the necessity of script 
and objects creating accessible output, but does this also need to be 
addressed as a warning to general authors in ATAG 2.0.  Whenever you 
write a script, you are in fact defining your own authoring tool.
