My understanding is that yes, this is the _only_ difference between the two. At least, that is how I treat the two. I am in the practice, though, of using sosofo-append when there are no characteristics to inherit. When writing programs using the SGML Flow Object Classes, this habit prevents any of the standard flow object classes being "mixed in" with the SGML flow object classes ... not that this should hurt, though, because if the SGML Flow Object Classes had inherited characteristics, then it would be crucial to have the sequence flow object class supported. Actually, I haven't tried it, but I wonder if you might even have problems using a sequence flow object with JADE's SGML back end (ie. does the JADE SGML back end support the sequence flow object in the flow object tree?). But as you said ... that would be more philosophical musings, as I just use sosofo-append when writing the SGML transforms. ........... Ken -- G.
